There are a few numbers that do not need signs. You do not have to sign when timing something.
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
rules of operation sign of numbers
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.
If two numbers have the same sign, their product is positive. If two numbers have opposite signs, their product is negative. So the answer is 'yes'.

An expression does not contain an equality sign.
That is called an expression.
This is a mathematical "expression".

2×+4×-5 An expression does not have an equal sign but can be solved has numbers, variables, and at least one operation
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.
