Hi guys, so today in class I had a surprise maths test and im not sure wether my answers were correct, so my option was to ask you guys since ur so awesome with it <3
So two of them were:
What is (-2) to the power 3?
Given that m= 2 and n=6, what is mn squared?
These were the most confusing ones for me, it will help me a lot the next time I get a test
Question 1: (-2)3
(-2) * (-2) * (-2) = answer
(-2) * (-2) = 4
4 * (-2) = -8
answer = -8
Question 2: (mn)2
m = 2
n = 6
(2*6)2 = (12)2
12 * 12 = 144
answer = 144
No problemo! Happy to help
I love math!
K just one more
Is the answer 19 or 23?
Me and my math teacher were debating this one lol.
Plz help me settle the debate @JonnyGamer
The answer is 24
42 - 21 = 21
21 + 3 = 24
42 + 3 = 45
45 - 21 = 24
(42) + (-21) + (3) can be rewritten in 6 ways, thanks to the communative property of addition
drop de doodle do
Mayb im wrong bcz I thought that you have to use BODMAS and so I did:
21+3 = 24
I literally asked the kindergarten teacher for help lol
If it was: 42 - (21 + 3)
then the answer would be 18
Oh okay thanks for clearing this up

I’m in eighth grade o-O
