#2: Accurately writes equation

Represent the same four cards that say "-5" as multiplication. Write a multiplication equation.

Integer Cards--Mr. Kovalik removes two cards when playing the integer card game. The cards he removes are two, -3 point cards.

If he gets rid of these penalties, how will this affect his score?

Write a multiplication equation to represent the change to your test score.

SPICY--Try if you have time.

BE CREATIVE--Find multiple ways of getting a value of -18 through according to the criteria:

a) Use one positive and one negative number and multiplication.

b) Use only negative numbers and addition.

Derek wrote the following addition expression to represent the money he has spent on hats for Among Us:

-2+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)+(-2)

Help him represent the total amount of money he has spent by writing an equivalent multiplication equation.
