Question

How do you solve `-132+ -7`?

Answer 1

`=-139`

Explanation:

`-132+ -7`
`=-132-7`
`=-139`

Answer 2

`-139`

Explanation:

The word "solve" is usually used for equations rather than expressions or calculations.

"Solve" implies finding the value for a variable which will make an equation true. It would be more correct to say "simplify", "determine" or "calculate"

We are adding integers :

`(-132)+(-7)` means start from 0, go 132 to the left down the number line and then another 7 down the number line, to bring us to `-139`

`(-132)+(-7) = -132-7 = -139`

Answer 3

`-139`

Explanation:

Think of + as 'put with'

Think of - as 'remove from'

So we have `-132` put with `-7`

This gives us a total of `-132-7= -139`

You would have been taught that putting two unlike signs next to each other give a final sign of minus:

`" " -3+ -2=-3-2=-5`

And that putting like signs next to each other gives a plus:

`" "-3--2=-3+2=-1`

`--3--2=+3+2=5`
