This question should be removed because there is no correct answer.
==============================================================================
For all 1st graders, who are so shocked how could've I not guessed the obvious 'x':
(22-11)-1x2 = (11)-2=9
9 is not equal 20, so 'x' is not the correct answer.
How Do I Remember the order of operations ? BODMAS !
B
Brackets first
O
Orders (ie Powers and Square Roots, etc.)
DM
Division and Multiplication (left-to-right)
AS
Addition and Subtraction (left-to-right)
storm, i told you, dont follow bodmas for the numbers game, just go from left to right, i knw your a math geek but this is a simple game for ppl who are and aren't math challenged. so try n forget ur 1st grade books when ur playing simple games online for fun
