Question

for x=1/10,y= -3/5, z= 7/20 find the value of the expression (x- y)- z and x- ( y -z)​

Answer 1

given that

X= 1/10 and y= -3/5 and z=7/20

so ( x- y) - z=

[ 1/10- (-3/5)] -7/20

so (1/10 + 3/5 )- 7/20

[7/10- 7/20]= 7/20

again; A/C qué

x-(y-z)=

1/10 -(-3/5 -7/20)

[1/10- -5/20 ]=

so 1/10+5/20=

7/20 ans
