Answer 1

a) 5x100x2=
500x2=1000
4x59x3=
236x3=708
b)42-2x(18-9)=
42-2x9=
42-18=24
(9+8)x(3+4)=
17x7=119
c)5x4x3=
20x3=60
6+5x9=
6+45=51
d)6+7x18-5x10=
6+126-50=
132-50=82
6x(2+18-10)=
6x(20-10)=
6x10=60

Answer 2

a) 5 x 100 x 2 = 500x2 = 1000
4 x 59 x 3 = 236 x 3 =708

b) 42 -2 x ( 18-9) =  42 - 2 x 9 = 42-18=24
(9+8) x ( 3 + 4) = 17 x 7 = 119

c) 5 x 4 x 3 = 20 x 3 = 60
6 + 5 x 9 = 6 + 55 =61

d) 6 + 7 x 18 - 5 x 10 = 6 + 126 - 50 = 6 + 76 = 82
6 x ( 2 + 18 - 10 ) = 6 x (20 -10) = 6 x 10 = 60
