What is a math expression?
An expression is the sum (or difference) of two or more terms. Example 3x + 2y is an expression.It is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have an expression if there is not an = signYes the 6 + 1 part is an expression. If you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence.

What is the expression for x equals 3 and y equals 6?
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
