What do they mean by 4 years older than twice her brother's age?

Obviously, you don't like math or spell checking(by the I'm sure you mean then, which should be than;thank me later).The way you learn in 6th grade is this:When your talking about age, older mean add and younger means subtract. Twice would mean double or times(multiplied by) two. Then there's than. That means you switch them. In this case you would "twice" the number THEN add 4.For example, let's say your brother is four and you she is y years old. How old are you?4(2)+4=YYou would write it out as an equation.The first 4 representing her brothers age, the two "twice", the 4 for the "four years older", and for "her"8+4=YMultiple first. Remember PEMDAS(Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction)12=YAddY=12RewriteIf I she is 4 years older than twice her brother's age, 4, then she would be 12. or (as in your case) The term 4 years older than twice her brother's age means double then added 4, with the equation x(brother)2+4=YPut as a sentence
