Question

I need a few sums using parenthesis

Eg. 4-(3+x)
6-(3x-4[1-x])

Answer 1

8-(6+x)
9-(8x-6[2-x])
12-(4x+3[2+x(3+x)]
9+(3x-4[12x-24(3x+5)+(6x+4)]
24+(5x+7[x-5(3x-6)+(7x+6)(8x+8)]

Answer 2

1) 6÷(3 x 4)+2
2) (1.2x3)+(3.2÷1.6)
3) (4.44+6.66)÷2
4) ([2 x 4] + 9)-12
5)  {( 10 - 9 ) x (1 - 0.2) } - 3
