Question

98-(7×3+12)+5×3. 9×(1+49:7:7)-16:8×(5-6:2). 4×(24:3-4)+(64:8:4+6)×2 . 56+(54:9×2)-6×7. va rog frumos

Answer 1

98-(7x3+12)+5x3=
98-(21+12)+15=
98-33+15=
65+15=80

9x(1+49:7:7)-16:8x(5-6:2)=
9x(1+7:7)-2x(5-3)=
9x(1+1)-2x2=
9x2-4=
18-4=14

4x(24:3-4)+(64:8:4+6)x2=
4x(8-4)+(8:4+6)x2=
4x4+(2+6)x2=
16+8x2=
16+16=32

56+(54:9x2)-6x7=
56+(6x2)-42=
56+12-42=
68-42=26

Answer 2

98-(21+12)+15
98-33+15=80

9x(1+1)-16:8x(5-3)
9x2-2x2=18-4=14

4x(8-4)+(2+6)x2
4x4+8x2=16+16=32

56+(6x2)-6x7
56+12-42=26
