Question

What is the answer to 120x+(-2x)

Answer 1

We have that

`120x+(-2x)`

Remember that if you multiply plus and minus you get minus. Check out this table for sing multiplication

In other words, if you multiply two sings that are the same, you get a plus. Otherwise, you'll get a minus.

Therefore,

`120x+(-2x)\rightarrow120x-2x\rightarrow118x`

The answer is 118x
