is 65-53 = 13?

Hi,

According to me the logic and answer should be

5 4 = 45-36 =9

Add firs two digits(5 4) :  5+4 = 9

Multiply the result (5+4 = 9) with the first digit (5) : 9 X 5 = 45

Multiply the result (5+4 = 9) with the second digit (4) : 9 X 4 = 36.

Therefore the answer should be

9 4 = ? = ?

Add two numbers 9+4 = 13

Multiply the result (9+4 = 13) with the first digit (9) : 13 X 9 = 117

Multiply the result (9+4 = 13) with the second digit (4) : 13 X 4 = 52.

9 4 = 117-52 = 65

*Note 6 7 = 78-51 =27 is inconsistent with said solution and should be 6 7 = 78-91 = -13

94=117-52=65.

Am I Right?

I think where you have written 51, there should be 91.
