If symbols do not have an equals then it is an expression.
That is called an expression.
An expression does not contain an equality sign.
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.

Rules of operators additon and multiplication (+) + (+) = + (+) + (-) OR (-)+(+)= sign of bigger number (-) + (-) = -(operation is addition but sign is -) (+) * (+) = + (-) * (-) = + (+) * (-) OR (-)*(+)= -
If there is an equal sign, it is called an equation; if there is a less-than, a less-than-or-equal, a greater-than, or a greater-than-or-equal sign, an inequality; if there is none of these, an expression.
2×+4×-5 An expression does not have an equal sign but can be solved has numbers, variables, and at least one operation
An "expression", is part of a number sentence that combines numbers and operation signs but does not have an equal sign" Example: x/y , when x=10 and y=5 , the assumption of this expresssion is 10/5 or 2. Or: 2+3 , the assumption of this expression is 5 even though no equal sign is present. Lyle Larson 4th grade Southern California
There are a few numbers that do not need signs. You do not have to sign when timing something.
