408-12×24 = 408 - 288 = 120
(46+28)×60 = 74 x 60 = 4440
42×50-17 = 2100- 17 = 2083
32+105÷5 = 32 + 21 = 53
420×(327-238) = 420 x 89 = 37380
(4121+2389)÷7 = 6510 ÷7 = 930
3.416÷(0.016×35) = 3.416 ÷0.56 = 6.1
0.8×[(10-6.76)÷1.2] = 0.8 x(3.24÷1.2) = 0.8 x 2.7 = 2.16
5.67×0.2-0.62 = 1.134-0.62 = 0.514
0.4×0.7×0.25 = 0.4 x 0.25 x 0.7 = 0.1 x 0.7 = 0.07
0.78+5.436+1 = 6.216 +1 = 7.216
30.8÷[14-(9.85+1.07)] = 30.8 ÷ (14 - 10.92) = 30.8÷3.08 = 10
[60-(9.5+28.9)]÷0.18 = (60- 38.4)÷0.18 = 21.6 ÷0.18 = 120
2.881÷0.43-0.24×3.5 = 6.7 - 0.24 x3.5 = 6.7 - 0.84 = 5.86
20×[(2.44-1.8)÷0.4+0.15] = 20x (0.64 ÷0.4 +0.15)= 20x(1.6 +0.15) = 20 x1.75 = 35
28-(3.4+1.25×2.4) = 28 - (3.4 + 3) = 28 - 6.4 = 21.6
2.55×7.1+2.45×7.1 = (2.55 + 2.45) x7.1 = 5 x7.1=35.5
0.8×〔15.5-(3.21+5.79)〕 = 0.8 x (15.5 - 9) = 0.8 x 6.5 = 5.2
(31.8+3.2×4)÷5 = (31.8 + 12.8)÷5 = 44.6÷5 = 8.92
