Question

\[\sf{X+Y}\]\[\quad=\]\[\quad\sf W?\]

Answer 1

Nope.\[\mathsf{x + y = z} \quad(\text{Source: OpenStudy homepage)} \]

Answer 2

K, I got what the question is. ;)\[24 + 25 \text{ mod }26 \implies 23\implies W \]

Answer 3

\[\sf{X+Y}\]\[\quad=\]\[\sf {\cancel{W?}}\]\[\sf Z\]

Answer 4

X is the 24th letter.
Y is the 25th letter.

There are 26 total letters, so basically if you add 24 + 25... you start again from 1 when you reach 26.

Answer 5

\[X + Y(\text{in letter modular arithmetic)} = 24 + 25 \text{ mod }26 = 49\text{ mod }26 = 23 = W \]

Answer 6

I don't think that there's something really known as "letter modular arithmetic". lool

Answer 7

huh?
