tolong pake cara ya kaka
1. 514 – (-45) + 34 =
Jawaban:
1. 514 – (-45) +34 = 514 + 45 +34 = 1.293
2. 400 + (-230) – (-10) = 400 -230 +10 = 180
3. -40 +300 +15 = 315 – 40 = 275
4. 315 – (-176) = 315 + 176 = 491
5. 101 +221 – (-35) = 101+ 221+35 = 357
6.
7. -120 + (-40) = -120 – 40 = -160
8. 117 -(-9)+25= 117+9+25 = 151
9. -35 – (-100) +50 = -35 + 100 +50 = 115
10. 76 + (-25) -50 =76 -25-50 = 1
untuk no 6 coba kamu kerjakan sekaligus untuk latihan
Penjelasan dengan langkah-langkah:
Mohon diingat :
Jika – (-1) itu = plus jadi +1
kamu perhatikan no 1,2,4,5,8,9
Jika -1 – 1 = -2
itu sama seperti -1 + -1 = -2
