When we have mixed signs we need to make it a negative. A plus and a minus or a minus and a plus are made into a minus by default.
With that in mind the question would not turn into 1 - 2 =
From here we take the sign of the bigger number. The bigger number would be negative 2 and we put it as the first part of our solution
This next step might be easier with a number line from -5 to 5
We start at positive 1 on the number line. From here we need to go left because when subtracting you go left. We move two spaces to the left. So the one goes to 0 and then it goes to -1
The answer would turn out to be <u>negative one</u><u>(</u><u>-1</u><u>)</u>
<u>1</u><u> </u><u>-</u><u> </u><u>2</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>1</u>

Answer:
10
Step-by-step explanation:
C = 0.75 + L
For L = 3 ; Cost, C = 3.75
3.75 = 0.75 + 3L
3.75 - 0.75 = 3L
3 = 3L
L = 3/3
L = $1
C = 0.75 + 1L
If amount spent is $10.75; C = 10.75
10.75 = 0.75 + L
10.75 - 0.75 = L
10 = L
Number of letters = 10
