Answer:
the difference between 15 and 11 is 4
Step-by-step explanation:
Okay first let's think about this like they are on a number line they both are on the right side of the number line so we don't need negatives
they both have 10 so
15 - 10 = 5
11 - 10 = 1
now we subtract what we have left
5 - 1 = 4
