### What does expression mean in math?

### What is a true sentence in math?

A sentence is made up of two expressions connected by an equal sign or an inequality sign (such as <). If there's an '=' sign, it's an equation, otherwise it's an inequality.

### Is equation the same as a problem?

An equations is a math sentence that asserts the quality of two expressions. Basically it's a math sentence that contains a variable and and equal sign. Is it a problem? Only if you have to solve it! It's easily solved by doing the inverse operation stated with the variable. Ex: n - 32 = 16 To solve you ADD 32 to both sides of the = sign. (to each expression) a - 32 + 32…
