There are a few numbers that do not need signs. You do not have to sign when timing something.
A mathematical expression has numbers and operation signs with no equal sign. Equations, on the other hand, do contain equal signs.

Algebraic expression
if there are no comparison signs (equals or inequalities, ie =, >, < etc) then it is an expression, eg "x + 5" If there is a comparison sign which is not equals, then it is an inequality, eg "x > 5"
A mathematical expression is a mathematical phrase that consist numbers variables and signs of operation example: x(variable) + 5(number)=7 so the value of x is 2 -Kennethn 10 yrs. old :]
An expression does not contain an equality sign.
No, replacing a negative variable with a negative number does not automatically make the number positive. The sign of the number is determined by the operation being performed. In mathematical operations, the signs of the numbers involved must be taken into consideration to determine the final result. Simply replacing a negative variable with a negative number does not change the inherent negativity of the number.
