1 + 2 = 21 2 + 3 =36 3 + 4 = 43 4 + 5 =?
And it is not 54

Answered by admin @ 20/08/2021

4 + 5 = 58 if 1 + 2 = 21 2 + 3 =36 3 + 4 = 43

Step-by-step explanation:

One solution

1 + 2 = 12 + 9 = 21

2 + 3 = 23 + 13 = 36

3 + 4 = 34 + 9 = 43

4 + 5 = 45 + 13 = 58

a + b = ab + 9 / 13 alternatively

Another way

1 + 2 = 21 + 0 = 21

2 + 3 = 32 + 4 = 36

3 + 4 = 43 + 0 = 43

4 + 5 = 54 + 4 = 58

a + b = ba + 0 /4 alternatively
