Answer 1

(48*34)/51=32

1) 48*34=1632

2) 1632/51=32

(54*38)/57=36

1) 54*38=2052

2) 2052/57=36

(32²-31²)²=(32-31)²(32+31)²=1²*63²=63²=3969

63*63=3969

22+(28*21)-11=11+588-11=599

1) 28*21=588

2) 588+22=610

3) 610-11=599

125+957+(1075/43)=1082+25=1107

1) 1075/43=25

2) 125+957=1082

3) 1082+25=1107

1132-375-(1024/32)=757-32=725

1) 1024/32=32

2) 1132-375=757

3) 757-32=725

29+(11*(18²-54))=2999

1) 18*18=324

2) 324-54=270

3) 270*11=2970

4) 2970+29=2999

(5*10²)-2*(441/21-6)²=(5*100)-2*(21-6)²=500-2*15²=500-2*225=500-450=50
