Does -7 • [-8] = 7• 8

Hey there!

Guide:

• Negative & negative = positive

• Positive & positive = positive

• Negative & positive = negative

• Positive & negative = negative

• Positives are above 0

• Negatives are below 0

• Negatives are on the left side of the number line

• Positives are on the right side of the number

Answering your question

-7 * -8 = 7 * 8

-7 * -8 = 56

7 * 8 = 56

56 = 56

YES they are equivalent/equal to each other because both of them equal positive 56.

• It wouldn’t be equivalent if one is a negative number and the other one is positive (even when it looks like the same number). If both numbers are positives / negatives with the same number then they’ll most likely be equivalent/equal to each other!

Good luck on your assignment and enjoy your day!

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
