Great. A multiple choice question with no choices. Find the expression that equals 8.
Anything that equals 12.
Whatever expression equals 22.
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
-2-2 = -4
Temperature is constant.

x=y-8 z=x+12
It is 9
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.
The commutative property.
Yes.Expressions are just javascript, so they can access any global variables on the page.The following works:var w = 10
An algebraic expression can have a mixture of numbers and variables, but it does not contain an equals sign.
An expression does not have an equals sign, An equation has an equals sign,
-7

It is an equation ... Anything with an equals is an equation 2+b=6 Anything without an equals is an expression 2+a
