Question

Calcule: 1-{4-2[2+5+2*(2-8+2+8-2)]}

Calcule: (-5)*(3/3)*2+3*([3-3+1+1-2-2+2+2-1]-32)

Calcule: -3{-2[5+2-1(2+3-3)]-1}​

Answer 1

A) 4-2[2+5+2*(2-8+2+8-2)]} =

4-2[2+5+2*(2]}

4-2[2+5+2*(2]}

4- 2[2+5+4]

4- 2[11] =4 -22= -18

B) (-5)*(3/3)*2+3*([3-3+1+1-2-2+2+2-1]-32)

(5)*(3/3)*2+3*([1]-32)

(5)*(3/3)*2+3*(-31)

5.2+3.(-31)

10-93= -83

c) 3{-2[5+2-1(2+3-3)]-1}

3{-2[5+2-1(2)]-1}

3{-2[5]-1}

3{-10-1}

3{-11}= -33
