strange math

$2(5)(6) + 1 = 61$

In the first statement (2=3=13)

If you multiply the first 2 numbers ( 2 = 3 =13)

you get 6 and if you multiply 6 by 2 you get 12 and if you add one to twelve you get 13 !

so the steps we followed are to get the last number is

1)multiply the 1st 2 numbers

2)to what you have got now multiply it by 2

3)And add 1 to get the answer

lets try this with the second one:

3=4=25

the first two numbers are 3 &4 so we multiply them

we get 12 lets multiply 12 by 2 it is 24 and

and 1 to

24 we get 25

so with the last one

5 = 6 = ?

so 5 x 6 = 30

30 x 2 = 60

and 60 + 1 is 61 so the answer is 61

$5^2+6^2=61$
