How to subtract positive and negative numbers?
Subtracting positive and negative numbers can be done by following some simple rules.
- If you are subtracting a positive number from a positive number, it's just normal subtraction.
- If you are subtracting a positive number from a negative number, start at the negative number and count backwards.
- If you are subtracting a negative number from a negative number, turn the two signs into a plus sign and add the numbers.
- If you are subtracting a negative number from a positive number, turn the subtraction sign followed by a negative sign into a plus sign and add the numbers.
Applying the above gives us:
Difference in Elsa and Jesse's money = 45 - (-30) = $75
Thus, Elsa has $75 more than Jesse
