Safety in numbers.
in maths, an expression is an equation with no equals sign. equation.............2+2=4 expression..........2+2
an expression is a sum without an equals sign e.g: 2x+4y
to evaluate an algebraci expression replace ech variable with a number. then follow the order of operations to dimply the expressio. Hope that helped :)
Any combination of numbers, variables, and symbols, that you can calculate (evaluate) to get a number (after replacing each variables with some number).
