If ab is not equal to 0, find the absolute value of a + b

If ab is not equal to 0, find the absolute value of a + b

Ab is not equal to 0,
If a and b are both positive,
Absolute value of a + absolute value of b =1+1=2
When both a and b are negative,
Absolute value of a + absolute value of b =-1+(-1)=-2
When a and b are different,
Absolute value of a + absolute value of b =-1+1=0

If a is not equal to 0 and b is not equal to 0, then the absolute value of ab is ab+ the absolute value of a+b is b

If a >0, b >0, ab+a+a+b, b=1+1+1=3, b <0, ab+a+, ab+a+a+b, b=-1+1+(-1)=-1, if a <0,b>0, ab+a+b, b.
