Answer 4

@casscatanzar84, What do you think/

Answer 5

there are 3 numbers

113,47
43,72
26,9

the first expression is A and the second is B

so what may be the question here ?

for example what is true ?

A > B

A = B

A < B

Answer 6

any idea ?

Answer 7

Find out The numerical value of A - B  and the numerical value of B - A.

To prove

As given

The expression 113.47 - (43.72 - 26.9) represents A.

The expression 113.47 - (26.9 - 43.72) represents B.

Thus

A - B =  113.47 - (43.72 - 26.9)  - ( 113.47 - (26.9 - 43.72))

First solving the bracket terms.

A - B =  113.47 - (43.72 - 26.9)  -  113.47  + (26.9 - 43.72)

        = 113.47 - 16.82 - 113.47 - 16.82

        =  113.47  - 113.47 - 16.82 - 16.82

        = -33.64

Therefore the value of A- B is -33.64.

Thus

B - A = 113.47 - (26.9 - 43.72) - (113.47 - (43.72 - 26.9))

First solving the bracket terms.

B - A = 113.47 - (26.9 - 43.72) - 113.47 + (43.72 - 26.9)

        =  113.47 + 16.82 - 113.47 + 16.82

        = 33.64

Therefore the value of the A - B is -33.64 and B - A is 33.64
