bonjour
1 [2x(100+2)] - 7
= (2 x 102) - 7
= 204 - 7
= 197
2 [(8+1) x 9 x 2] +(8x100)
= (9 x 18) + 800
= 162 + 800
= 962
3 (50-3) x 5-6
= 47 x 5 - 6
= 235 - 6
= 229
4 [[(5x9) - 4] x 2 x10] - 3
= [(45 - 4) x 20] - 3
= (41 x 20) - 3
= 820 - 3
= 817
5 (20+5+25) x 4 +7
= 50 x 4 + 7
= 200 + 7
= 207
6 [[(6x8) +2] x 10] +(45x9)
= [(48 + 2) x 10] + 405
= 50 x 10 + 405
= 500 + 405
= 905
7 (7 +3+5) x (9 x4)
= 15 x 36
= 540
8 (100 - 6-1) x10
= (100 - 7) x 10
= 93 x 10
= 930
9 (100-10-3) x (6+5)
= (100 - 13) x 11
= 87 x 11
= 957
10 [(2x 10) +6] x 9 +(30+10)
= (20 + 6) x 9 + 40
= 26 x 9 + 40
= 234 + 40
= 274
