Question

31100-(4180*3+236*8)=
(2600-2320)/4+140*3
5110*6-99/33=
8130*5+72/24=
7150*6-70/14=

Answer 1

7150 * 6 – 70 / 14 = 42895
7150*6=42900
70/14=5
42900-5=42895
8130 * 5 + 72 / 24 = 40653
8130*5=40650
72/24=3
40650+3=40653
5110 * 6 – 99 / 33 = 30657
5110*6=30660
99/33=3
30660-3=30657
(2600 – 2320) / 4 + 140 * 3 = 490
2600-2320=280
280:4=70
140*3=420
 70+420 = 490
31100-(4180*3+236*8)=16672
14180×3=12540
 236×8=1888
12540+1888=14428
31100-14428=16672
