Here are the solutions for the integer addition and subtraction problems.
Step-by-step Calculation:
1) $(-90) + (-10)$
Both numbers are negative, so we add their absolute values ($90 + 10 = 100$) and keep the negative sign.
Result: -100
2) $(459) + (254)$
Both numbers are positive, so we simply add them together.
$459 + 254 = 713$
Result: 713
3) $(-7) + (242)$
The signs are different. We subtract the smaller absolute value from the larger one ($242 - 7 = 235$). Since 242 is positive and larger, the answer is positive.
Result: 235
4) $(71) + (180)$
Both numbers are positive.
$71 + 180 = 251$
Result: 251
5) $(-333) + (-211)$
Both numbers are negative. Add absolute values ($333 + 211 = 544$) and keep the negative sign.
Result: -544
6) $(-312) - (471)$
Subtracting a positive number is the same as adding a negative number: $-312 + (-471)$. Both are negative, so we add absolute values ($312 + 471 = 783$) and keep the negative sign.
Result: -783
7) $(-161) - (-374)$
Subtracting a negative number is the same as adding a positive number: $-161 + 374$. The signs are different. Subtract absolute values ($374 - 161 = 213$). Since 374 is positive and larger, the answer is positive.
Result: 213
8) $(-232) + (-107)$
Both numbers are negative. Add absolute values ($232 + 107 = 339$) and keep the negative sign.
Result: -339
9) $(381) + (298)$
Both numbers are positive.
$381 + 298 = 679$
Result: 679
10) $(-173) + (450)$
The signs are different. Subtract absolute values ($450 - 173 = 277$). Since 450 is positive and larger, the answer is positive.
Result: 277
11) $(-181) + (292)$
The signs are different. Subtract absolute values ($292 - 181 = 111$). Since 292 is positive and larger, the answer is positive.
Result: 111
12) $(239) + (-105)$
The signs are different. Subtract absolute values ($239 - 105 = 134$). Since 239 is positive and larger, the answer is positive.
Result: 134
13) $(-160) - (-463)$
Subtracting a negative becomes addition: $-160 + 463$. Signs are different. Subtract absolute values ($463 - 160 = 303$). Since 463 is positive and larger, the answer is positive.
Result: 303
14) $(-140) - (289)$
This is $-140 + (-289)$. Both are negative. Add absolute values ($140 + 289 = 429$) and keep the negative sign.
Result: -429
15) $(119) + (55)$
Both numbers are positive.
$119 + 55 = 174$
Result: 174
16) $(-276) + (-14)$
Both numbers are negative. Add absolute values ($276 + 14 = 290$) and keep the negative sign.
Result: -290
17) $(475) - (-155)$
Subtracting a negative becomes addition: $475 + 155$.
$475 + 155 = 630$
Result: 630
18) $(67) + (-77)$
The signs are different. Subtract absolute values ($77 - 67 = 10$). Since 77 is negative and larger in magnitude, the answer is negative.
Result: -10
19) $(-243) + (-385)$
Both numbers are negative. Add absolute values ($243 + 385 = 628$) and keep the negative sign.
Result: -628
20) $(381) - (70)$
Positive minus positive.
$381 - 70 = 311$
Result: 311
21) $(-307) - (-340)$
Subtracting a negative becomes addition: $-307 + 340$. Signs are different. Subtract absolute values ($340 - 307 = 33$). Since 340 is positive and larger, the answer is positive.
Result: 33
22) $(-453) + (421)$
The signs are different. Subtract absolute values ($453 - 421 = 32$). Since 453 is negative and larger in magnitude, the answer is negative.
Result: -32
23) $(-37) + (-489)$
Both numbers are negative. Add absolute values ($37 + 489 = 526$) and keep the negative sign.
Result: -526
24) $(-121) + (-443)$
Both numbers are negative. Add absolute values ($121 + 443 = 564$) and keep the negative sign.
Result: -564
25) $(-300) + (452)$
The signs are different. Subtract absolute values ($452 - 300 = 152$). Since 452 is positive and larger, the answer is positive.
Result: 152
26) $(198) - (-190)$
Subtracting a negative becomes addition: $198 + 190$.
$198 + 190 = 388$
Result: 388
