Step-by-step solution for: Adding and Subtracting Integers Worksheet | Math Printables ...
Here are the solutions for the integer addition and subtraction problems. I have worked through each one step-by-step to ensure accuracy.
1) (-464) + (-329)
* Both numbers are negative, so we add their absolute values and keep the negative sign.
* $464 + 329 = 793$
* Result: -793
2) (-92) + (171)
* The signs are different. Subtract the smaller absolute value from the larger one ($171 - 92$).
* $171 - 92 = 79$
* The larger number (171) is positive, so the answer is positive.
* Result: 79
3) (87) + (125)
* Both numbers are positive. Simply add them.
* $87 + 125 = 212$
* Result: 212
4) (-147) + (232)
* Signs are different. Subtract smaller from larger ($232 - 147$).
* $232 - 147 = 85$
* The larger number (232) is positive.
* Result: 85
5) (173) - (-153)
* Subtracting a negative is the same as adding a positive. So, $173 + 153$.
* $173 + 153 = 326$
* Result: 326
6) (-172) + (-68)
* Both are negative. Add absolute values ($172 + 68$) and keep the negative sign.
* $172 + 68 = 240$
* Result: -240
7) (138) + (437)
* Both are positive. Add them.
* $138 + 437 = 575$
* Result: 575
8) (441) + (399)
* Both are positive. Add them.
* $441 + 399 = 840$
* Result: 840
9) (-202) - (-169)
* Subtracting a negative becomes addition: $-202 + 169$.
* Signs are different. Subtract smaller from larger ($202 - 169 = 33$).
* The larger absolute value (202) is negative.
* Result: -33
10) (-193) + (171)
* Signs are different. Subtract smaller from larger ($193 - 171 = 22$).
* The larger absolute value (193) is negative.
* Result: -22
11) (-310) - (190)
* Subtracting a positive is just regular subtraction, or adding a negative: $-310 + (-190)$.
* Both are effectively negative. Add absolute values ($310 + 190 = 500$).
* Keep the negative sign.
* Result: -500
12) (349) + (-255)
* Signs are different. Subtract smaller from larger ($349 - 255 = 94$).
* The larger absolute value (349) is positive.
* Result: 94
13) (87) - (-97)
* Subtracting a negative becomes addition: $87 + 97$.
* $87 + 97 = 184$
* Result: 184
14) (-36) - (278)
* This is $-36 - 278$. Both terms contribute to the negative direction.
* Add absolute values ($36 + 278 = 314$) and keep the negative sign.
* Result: -314
15) (266) + (-483)
* Signs are different. Subtract smaller from larger ($483 - 266 = 217$).
* The larger absolute value (483) is negative.
* Result: -217
16) (-72) - (14)
* This is $-72 - 14$. Add absolute values ($72 + 14 = 86$) and keep the negative sign.
* Result: -86
17) (324) - (424)
* Signs are effectively different ($324 - 424$). Subtract smaller from larger ($424 - 324 = 100$).
* The larger absolute value (424) is being subtracted, so the result is negative.
* Result: -100
18) (16) - (165)
* Subtract smaller from larger ($165 - 16 = 149$).
* The larger number (165) is being subtracted, so the result is negative.
* Result: -149
19) (168) + (315)
* Both are positive. Add them.
* $168 + 315 = 483$
* Result: 483
20) (314) - (464)
* Subtract smaller from larger ($464 - 314 = 150$).
* The larger number (464) is being subtracted, so the result is negative.
* Result: -150
21) (426) + (-265)
* Signs are different. Subtract smaller from larger ($426 - 265 = 161$).
* The larger absolute value (426) is positive.
* Result: 161
22) (422) + (-493)
* Signs are different. Subtract smaller from larger ($493 - 422 = 71$).
* The larger absolute value (493) is negative.
* Result: -71
23) (287) + (-376)
* Signs are different. Subtract smaller from larger ($376 - 287 = 89$).
* The larger absolute value (376) is negative.
* Result: -89
24) (-323) + (298)
* Signs are different. Subtract smaller from larger ($323 - 298 = 25$).
* The larger absolute value (323) is negative.
* Result: -25
25) (-157) - (115)
* This is $-157 - 115$. Add absolute values ($157 + 115 = 272$) and keep the negative sign.
* Result: -272
26) (-125) + (-63)
* Both are negative. Add absolute values ($125 + 63 = 188$) and keep the negative sign.
* Result: -188
