<h3>What is defined by the term expression?</h3>
In mathematics, an expression is a sentence that contains at least two digits or variables and with at least each math operation.
Addition, simple arithmetic, multiplication, or division are all examples of math operations.
- a) Constant: a numerical value that is fixed.
- b) Variables: they have no fixed values. Values are assigned based on the requirement.
- c) Terms: could be constants, variables, or variables multiplied by constants/ (s). Each word in an expression is denoted by a '+' or '-' sign.
For, the given condition in question;
Ms. Morales wrote the sum of 5 copies of some number n.
Then again,
He again wrote 2 copies of the same unknown number n.
The expression becomes;
n = 42 + 5
n = 47
Thus, the value of the unknown value is found as 47.
