Maths Puzzle: If 2+3=10, What Does 5+6 Equal?

Need to find a pattern that fits all the given examples. Treating it as equation is not correct. So there must be extra steps. 2+3=5 5x2=10 (5 is half of 10 so x2 and we have the result) But does that pattern work with the rest? 3+4=7 7x2=14 x2 pattern didn't work. We're looking for 21 which is x3. For the first set, we had to x2, and 2 was the first number in the equation. Second one we had to x3, and 3 was the first number in the equation. Is that the pattern we're after? Let's try with the last example 4+5=9 9x4=36 That worked, so it seems we have to first add the 2 numbers and then multiply by the first number. 5+6=11 11x5=55 By using the pattern discovered above, we get 55 as the final answer to replace the question mark.
