(5+4+2)x5

(4-2)x8

(5-2)x7

9x(9-7)

8x(7-6)

6x(9x8)

Answer 1

8x(5+9)= 8x5 + 8x9 = 40 + 72 = 112

9x(7+6)= 9x7 + 9x6 = 63 + 54 = 117

7x(3+8)= 7x3 + 7x8 = 21 + 56 = 77

(9+7)x6 = 9x6 + 7x6 = 54 + 42 = 96

(5+4+2)x5=5x5+4x5+2x5=25+20+10 = 55

(4-2)x8= 4x8 -2x8 = 32 - 16 = 16

(5-2)x7= 5x7 - 2x7 = 35 - 14 = 21

9x(9-7) = 9x9 - 9x7 = 81 - 63 = 18

8x(7-6) = 8x7 - 6x8 = 56 - 48 = 8

6x(9+8) = 9x6 + 6x8 = 54 + 48 = 102
