Question

9)Si: A = 4 - [2 - (3 - (-1 + 4)) - (1 - 5) - 5]
B = [2 - (-1) + (1 - 9) - (+25)] ÷ [1 + (+4)]
hallar el valor de: A - B

Answer 1

A = 4 - [2 - (3 - (-1 + 4)) - (1 - 5) - 5]

A = 4 - [2 - (3 - (+3)) - (-4) - 5]

A = 4 - [2 - (3 -3) + 4 - 5]

A = 4 - [2 - (0) -1 ]

A = 4 - [2 - 1 ]

A = 4 - [ 1 ]

A= 4 -1

A = 3

B = [2 - (-1) + (1 - 9) - (+25)] ÷ [1 + (+4)]

B = [2 + 1 + (-8) -25] ÷ [1 +4]

B = [ 3 -8 -25] ÷ [+5]

B = [ -5-25] ÷ [+5]

B = [ -30] ÷ [+5]

B = -6

Hallar el valor de:

A - B

3 - (-6)

3 + 6

9

Answer 2

Respuesta:

$\mathrm{A=4-\left[2-\left(3-\left(-1+4\right)\right)-\left(1-5\right)-5\right]}$

$-\left(3-\left(-1+4\right)\right)=0$

$-\left(1-5\right)=4$

$-\left(2+0+4-5\right)=1$

$4-1=3$

$\boxed{\mathrm{A=3}}$

$--------------------------------------$

${\mathrm{B=\left[2-\left(-1\right)+\left(1-9\right)-\left(+25\right)\right]\div \left[1+\left(+4\right)\right]}$

$2+1+1-9-25\div1+4$

$\:2+1+1-9-25=-30$

$-30\div1+4=-30\div5$

$30\div5=6$

$\boxed{\mathrm{B=-6}}$

Hallar el valor de: A - B

A - B

A = 3

B = -6

3 - (-6) = 3 + 6 = 9
