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


#2

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


#3

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

Yass! Thank you @JonnyGamer those were the answers I wrote for the test! Tysvm!!


#5

No problemo! Happy to help

I love math! :smile:


#6

K just one more

42-21+3

Is the answer 19 or 23?

Me and my math teacher were debating this one lol.

Plz help me settle the debate @JonnyGamer


#7

The answer is 24

42 - 21 = 21
21 + 3 = 24

or

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


#8

Mayb im wrong bcz I thought that you have to use BODMAS and so I did:

21+3 = 24
42-24= 18


#9

I literally asked the kindergarten teacher for help lol


#10

If it was: 42 - (21 + 3)
then the answer would be 18


#11
