Answer:
-14.5
Explanation:
-11 - 3.5
Because 11 is already negative, when you subtract a number from a negative, think of -11 becoming "smaller" (smaller being -14, or -25).
When doing -11 - 3.5, think if it as adding 11 and 3.5 together !
When you add them together, you get 14.5, but 14.5 isn't correct, as that's a very large number compared to -11.
You add a negative sign to said -14.5, and that's your answer !
Subtracting from a negative is confusing, so I taught myself to think of it as adding the numbers as if they were positive and adding a negative sign !
