Answer 1

Salut!

a) 9500 - 123 * 24 + 96 : 6 * 56 =
= 9500 - 2952 + 16 * 56 =
= 6548 + 896 = 7444

b) 6019 + 100 : 10 : 10 - 123 * 45 =
= 6019 + 10 : 10 - 5535 =
= 6019 + 1 - 5535 =
= 6020 - 5535 = 485

c) 95 : ( 2050 - 2045 ) * ( 1811 - 39 * 39 ) =
= 95 : 5 * ( 1811 - 1521 ) =
= 19 * 290 = 5510

d) 35 * (1000 - 975) * ( 75 + 75 : 5 - 22 * 4)=
= 35 * 25 * ( 75 + 15 - 88 ) =
= 875 * ( 90 - 88 ) =
= 875 * 2 = 1750.
