630140 / 70 * 70 + 60 * 754 - 11223 / 87 = 675251
1) 630140 / 70 = 9002
2) 9002 * 70 = 630140
3) 60 * 754 = 45240
4) 11223 / 87 = 129
5) 630140 + 45240 = 65380
6) 675380 - 129 = 675251

98754 - 3268 * ( 6075 + 9980 - 15996 ) / 38 = 93680
1) 6075 + 9980 = 16055
2) 16055 - 15996 = 59
3) 3268 * 56 = 192812
4) 192812 / 38 = 5074
5) 98754 - 5074 = 93680

( 20000 - 5163 ) / 37 - 16006 / ( 4558 / 86 ) = 99
1) 20000 - 5163 = 14837
2) 4558 / 89 = 53
3) 14837 / 37 = 401
4) 16006 / 53 = 302
5) 401 - 302 = 99

( 18305 / 7 - 2880 / 18 ) * 74 - 157930 = 23740
1) 18305 / 7 = 2615
2) 2880 / 18 = 160
3) 2615 - 160 = 2455
4) 2455 * 74 = 181670
5) 181670 - 157930 = 23740
