QuestionSubtract the following pairs of numbers: 1. $9-(-2)$ 2. $-20-10$ 3. $13-(-63)$ 4. $28-14$ 5. $-10-0$ 6. $-33-33$ 7. $-18-(-12)$ 8. $-28-(-13)$ 9. $-18-(-40)$

Studdy Solution
Perform the addition operation.
$$-18 +40 =22$$The solutions to the subtraction problems are1. $9 - (-) =11$ . $-20 -10 = -30$
3. $13 - (-63) =76$
4. $28 -14 =14$ . $-10 -0 = -10$
6. $-33 -33 = -66$
7. $-18 - (-12) = -6$
8. $-28 - (-13) = -15$
9. $-18 - (-40) =22$
