Any mathematical calculation or formula combine numbers and/or variables using sums, differences, products, quotients (including fractions), exponents, roots, logarithms, trigonometric functions, parentheses, brackets, functions, or other mathematical operations.
In this way, expressions may not contain the equal sign (=) or any type of inequality. The expression above does not contain them. Anyway, we can write words to match the expression:
[tex] 3+(4 \times 12) [/tex]
In this expression we have a sum, a product and parentheses, so the answer is:
The sum of three and the product of four and twelve.
Or:
Three plus the product of four and twelve.
