(9-9)-(9-9)+(9+1)=10
(4 x 4) + (4 / 4)
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
That's a polynomial expression.
This is a mathematical "expression".
a numerical expression is just an expression without any equal or unequal signs, e.g. (a+2b)c or 5x-6y an equation shows two expressions with an equal sign, e.g. (a+2b)c = 53 or 5x-6y = 3k2-7k+21
(4*4)+(4/4) parentheses are not needed
(4 x 4) + (4 / 4)
4X4+4/4

A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.
An algebraic expression
An algebraic expression
An expression
simply put, an expression has no "equal to" sign (=). and equation has the "equal" to sign and and inequality has either one of these signs <, >
An equation with two equal signs is really to explicit equations (or three implicit ones). For example, expession 1 = expression 2 = expression 3 is equivalent to expression 1 = expression 2 AND expression 2 = expression 3 and, by transitivity, expression 1 = expression 3 So you need to solve two of the above three.
An expression does not contain an equality sign.
All expressions DO contain equals signs.
