-43

300

Numbers that are less than zero

negative numbers

300

-280 - 100 = -180 because you do 280 minus 100 and keep the negative sign.

When you already start negative, subtraction of a positive means going even lower. So you actually add up 280 and 100 to get 380 and then remember you are still negative, so -380.

400

The integers that come just before and just after -7.

-6 and -8

On a number line, do do -18 - 5, you start at -18 and then move right 5 to get -13.

Subtracting a positive means to move left. So from -18, you should move left 5 to get to -23.
