# Whats 9+10? Watch

1. What field are we working in?

For example, 9+10 in integers modulo 3 is 9mod3 + 10mod3 = 0mod3 + 1mod3 = 1.

Integers modulo 13 on the other hand, 9+10 = 6.

You smartass you... :^_^:
7. 9+10=18
8. Hmm, let's try a trig sub.

9 + 10 = 9*1 + 10*1 = 9*(cos^2(x) + sin^2(x)) + 10*(cos^2(x) + sin^2(x))
= 9*((cos(2x) + 1)/2 + sin^2(x)) + 10*(cos^2(x) - (cos(2x) -1)/2)
= 9/2(cos(2x) + 1) + 9sin^2(x) + 10cos^2(x) - 5(cos(2x) - 1)
= 9/2(cos(2x) + 1) + 9sin^2(x) + 10cos^2*(x) -5(cos(2x) + 1) + 10
= 9sin^2(x) - (1/2)(cos(2x) + 1) + 10cos^2(x) + 10
= 9sin^2(x) - cos^2(x) + 10cos^2*(x) + 10
= 9sin^2(x) + 9cos^2(x) + 10
= 9sin^2(x) + 9cos^2(x) + 9 + 1
= 9(sin^2(x) + cos^2(x) + 1) + 1
= 9(1 + 1) + 1
= 18 + 1
= 19
9. It depends what group you're working in. If you're working in a group containing the integers you'd just add them normally.

19! = 1.216451e+17
I make it 121645100408832000. It's not equal to what you said.

I thought that was an A2 Maths question.
The answer is 420 by the way.
