How do you do math expressions?
Well in math an expression is a finite combination of symbols that is well-formed according to rules that depend on the context. Symbols can designate numbers (constance), variables, operations, functions, and other mathematical symbols, as well as punctuation, symbols of grouping, and other syntactic symbols. The use of expressions can range from the simple: 3 + 5 it is as easy as 1 2 3 but as you get older your math expressions will get harder.
What is a sentence made up of numbers variables grouping symbols and operations?
That type of sentence is called a mathematical expression.
What are grouping symbols?
Grouping symbols are symbols such as parentheses or brackets, that indicate that the operations within them should be done first. When an expression contains more than one pair of grouping symbols, the computations in the innermost grouping should be done first.
