The joke answer is 21 but not mathematically accurate
ps if you posted as a joke, it's very old and already been done to death
its 910 because you put a 9, then you add a 10 next to it. Boom quick maffs
21 *gets smacked and called stupid*
its 69 cause 6+9+6x9=69 so its obviously 69

21
whats 9 plus 10 21
whats 9 plus 10 21
18
9 + 9 + 10 + 10 = 38
A=9 h=1 9+9+1=19
= 90 (9*10)
48 plus 22 plus 10 plus 10 plus 9 plus 1 is equal to 100.
Tautology?
9 + 10 + 29 - 10 = 38
It is 8.50
Its easy
10+11+9+3= 33
