Question

Is a+b+c=a+(b+c)=(b+a)+c?​

Answer 1

Answer:

May or may not

Step-by-step explanation:

let a=1,b=-5,c=6

a+b+c=1+(-5)+6=2

a+(b+c)=1+{(-5)+6}=2

(b+a)+c={(-5)+1}+1= (-3)(therefore not)

let a=1,b=2,c=3

a+b+c=1+2+3=6

a+(b+c)=1+(2+3)=6

(b+a)+c=(2+1)+3=7(therefore yes)

therefore may or may not.

Done.
