What is the location of the sum 11+(-5) with respect to 11 on a number line?
a: five units to the left of 11
b: five units to the right of 11
c: 11 units to the left of zero
d: 11 units to the right of zero

A is the answer. 5 units to the LEFT of 11. This is because even though the addition sign tells us to go the right side of the number line, the parenthesis number has a negative sign. Multiplying the signs will give 11-5 which will ask us to got LEFT of the number 11 on a number line.
