Question

PLEASE ANSWER! VERY IMPORTANT LAST IMPORTANT QUESTION! MUST BE CORRECT! POINTS GIVEN!

Emma said that when you multiply three negative decimals the answer will be positive. Use these numbers to answer the questions: –2.5, –3.8, –2.7, –4.5, 1.4

Emma changed her statement to say that when you multiply two negative decimals and a positive decimal the answer will be positive. Is Emma’s new statement always true, sometimes true, or always false? Write two equations to support your answer.

Answer 1

Emma is always. When solving, you use the PEMDAS method going from left to right.

Your equation would be something like " -2 * -2 * 4"
Because you would start with (-2 * -2) = 4 and then move to 4 * 4 = 16

If your equation were something like " -2 * 3 * -2"
You would do -2 * 3 = -6 and then move to -6 * -2 = 12

Remember "Two negatives = a positive"
