Question

PLZ HELP!! 39+(-20.4) When you answer can you plz show how you got the answer plz!!

Answer 1

It will be +18.6
Because (-20.4) is a negative number
Imagine a number line you would need 20.4 to get back to 0 since you will start at negative 20.4
39-20.4 is 18.6
So you have 18.6 left which will be on the positive side so that’s the answer
