Answer 1

(3×100-75):5=(300-75):5=225:5=45

3×[(100-75):5]=3×(25:5)=3×5=15

9+2×[30-4×(8-6:2)]=

9+2×[30-4×(8-3)]=

9+2×(30-4×5)=

9+2×(30-20)=

9+2×10=29

(2100-1965):(3×3):(25:5)×10=

(2100-1965):9:5×10=

135:9:5×10=

15:5×10=

3×10=30

4×4-{3×167-2×[3+4×(5+6×7)-8]}:9=

16-[501-2×(3+4×47-8)]:9=

16-[501-2×(3+188-8)]:9=

16-(501-2×183):9=

16-(501-366):9=

16-135:9=

16-15=1

960:10:2:8:3=

96:2:8:3=

48:8:3=

6:3=2

124+(368:8×9)-(128×3:4)=

124+(46×9)-(384:4)=

124+414-96=442

124+32:8×115-81:9:3×100=

124+460-300=284
