The first step in simplifying our expression is to simplify what is in the parenthesis.
In parenthesis, we have a negative number but it can be taken out to give
[tex]-22.75+18.3[/tex]From here we need to add (or subtract, depends on how you want to think of it) the two numbers.
This addition can be visualized on a number line. Imagine starting at -22.75 and then moving 18.3 units to the right, where will we land?
We will land at -4.45.
Hence, our answer is -4.45.
