Re: 48÷2(9+3)=?????
From Wiki:
A common shorthand is B. E. D. M. A. S. which is: brackets, exponents, division & multiplication, addition & subtraction.
This means that if a mathematical expression is preceded by one operator and followed by another, the operator higher on the list should be applied first. The commutative and associative laws of addition and multiplication allow terms to be added in any order and factors to be multiplied in any order, but mixed operations must obey the standard order of operations.
It is helpful to treat division as multiplication by the reciprocal (multiplicative inverse) and subtraction as addition of the opposite (additive inverse). Thus 3/4 = 3 ÷ 4 = 3 • ¼; in other words the quotient of 3 and 4 equals the product of 3 and ¼.
So basically if you make the "÷2" part equivalent to "*0.5" then you have all multiplication left and you get 288. Boom.
