Step-by-step solution for: 9 Adding and Subtracting Integers Worksheets to Teach with ...
Here are the solutions to the integer addition and subtraction problems. I have worked through each one step-by-step to ensure accuracy.
1) (-90) + (-10)
When adding two negative numbers, you add their absolute values (90 + 10 = 100) and keep the negative sign.
Answer: -100
2) (459) + (254)
Both numbers are positive, so we just add them together.
459 + 254 = 713
Answer: 713
3) (-7) + (242)
The signs are different. Subtract the smaller absolute value from the larger one (242 - 7 = 235). The larger number (242) is positive, so the answer is positive.
Answer: 235
4) (71) + (180)
Both numbers are positive.
71 + 180 = 251
Answer: 251
5) (-333) + (-211)
Both numbers are negative. Add the values (333 + 211 = 544) and keep the negative sign.
Answer: -544
6) (-312) - (471)
Subtracting a positive number is like adding a negative. So this becomes (-312) + (-471). Both are negative, so add the values (312 + 471 = 783) and keep the negative sign.
Answer: -783
7) (-161) - (-374)
Subtracting a negative number is the same as adding a positive. So this becomes (-161) + 374. The signs are different. Subtract the smaller from the larger (374 - 161 = 213). The larger number (374) is positive, so the answer is positive.
Answer: 213
8) (-232) + (-107)
Both numbers are negative. Add the values (232 + 107 = 339) and keep the negative sign.
Answer: -339
9) (381) + (298)
Both numbers are positive.
381 + 298 = 679
Answer: 679
10) (-173) + (450)
The signs are different. Subtract the smaller from the larger (450 - 173 = 277). The larger number (450) is positive, so the answer is positive.
Answer: 277
11) (-181) + (292)
The signs are different. Subtract the smaller from the larger (292 - 181 = 111). The larger number (292) is positive, so the answer is positive.
