#21

You in eighth grade as well??

#22

Yeh

#23

Ok lgbttt we’ll talk about this in ur gt @PartTimeFemale so we don’t clog up this topic and get flagged by someone. …

#24

Yeah, sure thingo
I was mistaken, I’ll brb at 4:00 Pacific time or so oop my bad :/

#25

Okay tysm @JonnyGamer!

#26

-2 to the power of 3 equals -2•-2•-2, -2•-2= 4 and 4•-2= -8, so (-2)^3= -8
(-2)^3 also equals -2^3 because 2•2•2•-1 still equals -8.

If the question is (mn)^2 than that is (2•6)•(2•6) which equals 12•12 which equals 144. If the question is mn^2 than it is 26^2 or 2(6^2) which equals 2•(6•6) which equals 2•36 which equals 72.

If the question is 42-21+3 the answer is 24. Why? Because of the Order of Operations, which is:
Parentheses ( )
Exponents sqrt(), ^x
Multiplication •
Divison /
Subtraction -
(Multiplication and divisor are done on the same step, from left to right. So if I had the problem 6/3•2 it wouldn’t be 6/6 it would be 2•2. Addition and subtraction are done on the same step, from left to right also.)

So because of this, 42-21+3 does not equal 42-(21+3) because that would mean 42-21-3 not 42-21+3.
42-21=21
21+3=24

I’m in seventh grade but I’m learning some High School Geometry and Algebra and a bit of calculus, because I’m weird and have no life.

#28

Is it not BODMAS?
Brackets
Of
Division
Multiplication
Subtraction

I dunno mayb u use something else but I use this method.

#29

Yall use gemdas

Groupings
Exponents
Multaplacation/divishion

#30

-8

The other one is 144

#31

You are correct on both.

#32

Its not 144.

The mathematical order states exponents come first, so you raise six to the power of two first to get thirty-six. Then you multiply it by two.

#33

over here in 7th

#34

we do PEMDAS

#35

Us in America use PEMDAS

Parenthesis
Exponents

Multiplication/Division

#36

I know

I just wasn’t paying attention

#37

Ooh bcz I’m not in America and we use BODMAS. Our maths isnt as complicated as yours

#38

Brackets can contain exponents, and that doesn’t show the order of operations, it just says what comes first.

#39

It depends. It might have been one or the other but if it was mn^2 it would be 72, but if it was(mn)^2 it would be 144.

#40

Its not 144.

The mathematical order states exponents come first, so you raise six to the power of two first to get thirty-six. Then you multiply it by two.

I think the wording implies that the product of mn is squared

Given that m= 2 and n=6, what is mn squared?

So ^ would translate to (mn)^2 = 144
