A Fascinating Calculation

Dividing by 7 yields this fascinating play of the numbers 1,4,2,8,5 and7. I am not going to spoil the fun by letting you on the pattern that emerges and other captivating properties that you might discover along the way.

Although feel free to write to us if you found anything that marveled you and we would definitely share it with the world.

Who knew division could be this much fun. am i right?

Have fun!

Something I mocked up for fun. Rooster teeth’s Maine compared to the height of their Team RWBY based on my earlier calculation of Maine’s Height when compared to his brute shot. I also added the blue figure to represent the height of an average male in America (which is how tall I am) to illustrate the staggering size difference .

I’d also like to point out why I choose to use RWBY characters.

1)I love the show I’m excited about the new season.

2) More importantly, they have canonically listed heights that make for an easy comparison.

The protractor and the Bunsen burner. Playing the recorder in music class. Drawing arcs and circles with a compass in geometry. These tools of the education trade become part of our lives for a semester or two and then we move on.

Today, NPR Ed begins a new series examining these icons of the classroom. We start off with a device that once was essential to higher-level math, in school and in the workplace, but now has all but disappeared:

The slide rule.

“Take your batteries out,” Jim Hus says, watching his pre-calculus students remove the AA batteries that power their calculators. “Let’s do those multiplication problems again.”

A million dollars is a ton of money, literally.

Here’s another Math calculation for you to practice:

The physician writes an order that a client can have 12 ounces of clear liquids at each meal and can supplement this with 10 ounces at each shift [7-3, 3-11, 11-7]. How many mL should the nurse document for the day shift [7-3] if the client took all of the ordered volumes? Record your answer using a whole number.



He can have 12oz with each meal & 10oz per shift. Write it out. Then mark each one that the client took during the RN’s shift [7-3].

Breakfast - 12oz [He had breakfast at 7am].
Lunch - 12oz [He had lunch at noon].
Dinner - 12 oz [The RN left at 3, so she wasn’t there to serve him dinner].

Shift 7-3 –10oz [This is the RN’s shift].
Shift 3-11 –10oz
Shift 11-7 – 10oz

Now, add it all together. 12oz + 12oz + 10oz = 34 oz

Next convert oz to mL, because that is what the question is asking you.

34oz = x mL
1x = 30 x 34
x = 1020mL

Note, the question threw in that extra “record your answer using a whole number” just to confuse you! Careful!

I have a working file selection form working.  Once you choose a file and hit submit, the volume is calculated and then updated in the box below the button.  This is a major feature that I have been learning for the past 2 or 3 weeks and I have it working.  This is a major milestone for my site.  I am seriously excited.  Now I just have to put it into a block or insert it into the certain type of content that it needs to go in!  

MH4: How Damage Calculation Works (Simplified)

I know what you’re thinking – this is going to be so complicated it will blow your mind. Luckily, it’s not! I’ll do my best to use layman’s terms as I write this guide. Once I get into weapon guides like Charge Axe, stuff like damage calculation becomes very critical in understanding how to effectively use, and choose, your weapon. I will take a top down approach in explaining how damage is calculated. I will NOT jump into all the details since this not meant to be overly complicated so this is a simplification.

Damage = [Physical damage] + [Elemental Damage] * Overall Defense

Overall defense is a set percentage that changes depending on the quest. That’s why “powered up” quests have monsters that have not only more HP, but are tougher to break parts as well (if it was just HP then there would be no difference, after all!). For generality sake, assume that:

Village:                  100%

Low Rank:             85-95%

High Rank:            75-85%

High guild/event:    70%

Yeah, so if you do the same quest in the online part of the game solo, you are battling a monster that is about 25% higher defense, they do this because you’ll typically be online with other players. Okay, let’s break down the formula for damage.

Physical Damage = [Power * Motion value * Effectiveness]

Power is just the weapon’s attack as shown divided by a special factor for that weapon. Here they are:

Hammer/Horn: 5.2

Switch Axe: 5.4

Great Sword: 4.8

Charge Axe: 3.6

Long Sword: 3.3

Insect Staff: 3.1

Lance/Gunlance: 2.3

Heavy Bowgun: 1.5

SnS/Dual Swords: 1.4

Light Bowgun: 1.3

Bow 1.2

So, if you have a Charge Axe with an attack of 648, it’s power = 180 (648 / 3.6). It would be considered the same power as a Great Sword with the attack power listed as 864, which also equals 180. (For those who are curious, you’ll notice guild quest weapons that are legendary start at like 180 and each LV go up 10. The one that are super high attack that doesn’t change and carry a -25% affinity are 230 power).

Awesome! But what if your weapon has affinity (chance of critical rate)? The calculation for the expected power is simple. Remember, a critical hit is 1.25x the attack power.

Expected Power = Attack x (1 + 0.25 x (critical rate/100))

So if the 648 Charge Axe carried a 25% affinity (the Shagaru Charge Axe) then its expected power is: 648 * (1 +0.25 * (25/100)) = 688 attack

So take that and divid it by the weapon factor. 688 / 3.6 = 191 power

Motion Values:

This is the value each attack has. Hunters go through a lot of trouble to figure out these numbers, typically by kicking small monsters to death than using one of a move then seeing how many kicks on top of that is required to kill it. The slower the animation = the higher the number = the more damage it does.

Motion Value List:

So let’s look at the Charge Axe and the initial draw to sword motion value is 17. The easiest way to think of it is that the weapon has a power of 191 and that is 100% of its power. The motion value is how much % of that power is used, so 17 = 17% of its total power (32). But we are not done; we have to take into consideration how effective the attack is to the specific body part of the monster. For Shagaru Magala, its head is weak so 65% effectiveness for cutting damage. So the damage if we do a draw to sword attack on its head is: 32 * 0.65 = 21 damage. Here’s how we got that:

648+25% affinity = 688 power / 3.6 = 191 expected power * 17 (motion) = 32 damage * 65% effectiveness = 21 damage! Phew!

But what if we attack its body, which is actually very tough (25% effectiveness). You would only do 8 damage! Yikes! Now you can see why pro hunters go for the head!

OK, we now can calculate physical damage, all we need now is elemental damage and we are all done! Luckily, elemental damage is much easier.

Elemental Damage Calculation

[Elemental power shown / 10 x effectiveness]

Continuing with the Shagaru Charge Axe, it has 230 dragon element. That means it has 23 (divide by 10) dragon power. Look up the effectiveness and you’ll see that Shagaru’s head is super weak to dragon, in fact 30%! You don’t have to worry about what attack you did, it doesn’t even matter – that is why weapons like SnS that hit a lot are good for dealing out elemental damage and Great Sword for example SUCKS at it. 23 is your default elemental attack power for any attack.

23 dragon attack * 30% effectiveness = 7 damage. So if you did a draw sword attack (like above) then you would do 21 physical damage + 7 elemental damage = 28 damage!

If an element is 0% effective on that monster’s part then you get NO elemental damage. Aw, well. To finish off the example, we said before that attacking Shagaru’s body is kinda dumb since it’s so tough – the dragon effectiveness is only 10% as well, so we get 8 physical damage + 2 elemental damage = 10 damage. Yuck.

Review + semi-advanced notes:

OK assuming we did a draw attack with the Shagaru Charge Axe on the Shagaru’s head, we would do 28 damage:

[648 * (1 +0.25 * (25/100)) = 688 / 3.6 = 191 * 0.17] * 0.65 + [230 / 10 = 23] * 0.65 = 28 Damage


After you calculate the damage from the attack power and motion value (or after you divined by 10 for elemental power), you then actually apply the sharpness modifier to it, then times it by the effectiveness:

Red:       0.50x attack, 0.25x element

Orange:  0.75x attack, 0.50x element

Yellow:   1.00x attack, 0.75x element

Green:    1.05x attack, 1.00x element

Blue:       1.20x attack, 1.06x element

White:    1.32x attack, 1.12x element

Purple:   1.44x attack, 1.20x element

Other Stuff

I do into great detail about the power up items and skills in this post of mine. Check it out if you wanna jump deep down the rabbit hole:

Bombs and attacks that deal set damage no matter what part you hit:

Bombs, gunlance shells, phial explosions on special charge axes, etc. deal damage that is set and does not change no matter where you hit. This is HUGE. As you saw above, attacking Shagaru’s body versus its head results in very different damage. These special items/weapons can attack any part and deal the same amount.

Know that:

Large Barrel Bomb = 50 damage

Large Barrel Bomb G = 150 damage
