a) x + 22 + (-14) + 52 = x + [ 22 + 52 ] + (-14) = x + 74 + (-14)

   = x + [ 74 + (-14) ] = x + 60

b) (-90) - (p + 10) + 100 = (-90) - p - 10 + 100 = - p - 90 - 10 + 100

    = -p - (90 + 10) + 100 = -p - 100 + 100 = -p + [ (-100) + 100] = -p

\(x+22+\left(-14\right)+52=x+60\)

\(\left(-90\right)-\left(p+10\right)+100=-90-p-10+100=-p\)

a)x + 22 + ( - 14 ) + 52

Đơn giản biểu thức:
a) x+22+(-14)+52= x+(22+52)+(-14)
= x+(74+ -14)
= x+60
b) (-90) - (p+10)+100= (-90)-p-10+100
= (-90 + -10) +100 -p
=(-100) + 100-p
= 0-p= (-p)

a) x  +22 + (-14) + 52

= x  + 60

a , x + 22 + (-14)+ 52 = x + 60

b , (-90) - ( p + 10 ) +100 = (-90) - p - 10 + 100 =  -p

a, \(x+22+\left(-14\right)+52\)

\(=x+\left(22+52\right)+\left(-14\right)\)

\(=x+74+\left(-14\right)\)

\(=x+60\)

b, \(\left(-90\right)-\left(p+10\right)+100\)

\(-90-p-10+100\)

\(=-p-\left[100+\left(-90\right)-10\right]\)

\(=-p+0\)

\(=-p\)

a, x + 22 + (- 14) + 52 = x + 60

b, - 90 - ( p + 10 ) + 100 = -90 - p - 10 + 100 = -p - 90 - 10 + 100 = -p - ( 90 + 10 - 100 ) = -p - 0 = -p

a) x + 22 + ( -14 ) + 52

= x + 22 - 14 + 52

= x + 8 + 52

= x + 60

b) ( -90 ) - ( p + 10 ) + 100

= -90 - p - 10 + 100

= ( 100 - 90 - 10 ) - p

= 0 - p

= -p
