Math multiplication trick

[jdubnyce]

Now do odd numbers with that method like 9 x 37. Don't use calculators and only that method

4.5 * 18.5

Or just learn your multiplication tables?

It's literally just repetitive adding. If you can add you can multiply. Yes, it's that simple once you study it diligently.

Nikkas always want gimmicks and tricks to replace what already works.

Optimization is not gimmicks

The American curriculum is archaic and bloated. Far from the best method of learning

That method won’t work as easy, but With numbers like that I do 9x30 which is 270, and then 9x7 which is 63, then add them together which is 333. I do that in my head.

those are the use of equalities

OP doesn't know about this here ..

x * y = (x/2) * (2y)

All these nerds here

Just use a calculator fakkits

use to hate that shyt in high school/college. No cheat sheets or put all your formulas on a single index card. You know what I don't have to do at work every day. Try and recall shyt from memory. Oh my code's fukked up. Let me go check out what they say on stack overflow and get it fixed. fukk outta here.

Work smarter harder use the tools available to you.

"Copilot, how do I highlight the cells that only have this bullshyt instead of that bullshyt?"

 

[Mike_Pipeson]

(10 * 37) - (1 * 37)

That's the method shown in the clip?

no accountant babble..

I do this naturally sometimes when doing calculations in my head. If you gotta calculate shyt all day I think you will find shortcuts like this by default.

 

[TEH]

I prefer to do my multiplications thecoli way

Certs x Abs = Dimes

here:

9​	37​
3​	111​
1​	333​

same method using 3 instead of 2




shouldda picked 2 primes

I prefer to do my multiplications thecoli way

6 figures x 6 certs... 12 figures x 3 certs... 6 figures x 6 certs... 12 figures x 3 certs... what kinda dumbass recursive shyt is this

its like when my cat sleeps on the keyboard at night and photoshop is open. shyt just undos and redos all night cause its just the right buttons under his ass

9x40 minus 27. 360 minus 27 = 333
