Question

The temperature was 80 and then fell 20. Write an addition equation to represent the problem.

Pls help

Answer 1

80+(-20)

Explanation:

total = 80

dropped = -20

equation = 80+(-20)

Answer 2

80 + (-20) = 60

Explanation:

At first glace, this equation would be

80 - 20 = 60

But, since it needs to be written as addition, it can be rewritten as

80 + (-20) = 60

Adding a negative number is the same a subtracting it! I hope this helps!
