It is a lot of numbers and letters, combined together with various mathematical operations and functions. Operations such as addition, subtraction, multiplication division, exponentiation etc; functions such as trigonometric ones, logarithms, factorials, etc.
An expression cannot have an equals sign (or a less than or more than sign) because then it becomes an equation (inequality).
So 3x2 + 2y/sin(x) - 23-x is an expression.

In maths a table is like a graph
Look in an advanced maths book.Improved answer:-If the discriminant of the quadratic expression is less than zero then it's not possible to factor it.
A expression in maths is a collection of terms without an equality sign.
Safety in numbers.
It looks like an upside-down "T".
A formula with an equal sign
> - greater than < - less than
Like this . . .B - 4 = 35and it is then an equation, not an expression.
2x
An equation has an equal sign, a expression does not.
it is a name of the Macbeth peron hahahahahaha 1 of my maths techers look like Macbeth :L
Um, not always but you never know. When i look at someone i like i tend to smile or just look away.
