1) - 62 + 44 = 44 - 62 = -18

2) -258 + 1.468 = 1.468 - 258 = 1.210

3) 27 + 15 + 413 = 42 + 413 = 455

4) (-34) + 248 + 64 = (-34) + 312 = 312 - 34 = 278

semoga jelas dan membantu ya

1. -62 + 44
= -18
2. -258 + 1.468
= 1.210
3. 27 + 15 + 413
= 42 + 413
= 455
4. ( -34 ) + 248 + 64
= 214 + 64
= 278
5. 447 + 213 + ( -217 )
= 660 - 217
= 443
6. 12 x 15 x ( -5 )
= 180 x ( -5 )
= -900
7. 3 x 7 x 11
= 21 x 11
= 231
8. 45 x ( -9 ) x 2
= ( -405 ) x 2
= -810
