In Roman numerals, M represents the value 1000. There is no limit to how many times M can be repeated in a Roman numeral representation, so it can appear as many times as needed to represent the desired value. For example, MMM represents 3000.
It is abs(54 - 7*n) or |54 - 7*n|

Four times a variable, named m, multiplied by itself four times. Technically (or pedantically) it is multiplied three times but that is one of the oddities of verbal expressions.
3n + 4

Let the number be x and so the expression is 4x -3
twenty four times a number and add 19

No, not all expressions contain variables. An expression is a mathematical phrase that combines numbers, variables, and mathematical operations. A variable is a symbol that represents a quantity that can vary, such as x or y. Some expressions may only contain numbers and mathematical operations, such as addition, subtraction, multiplication, and division. For example, "3 + 5" is an expression that only contains numbers and the addition operation. However, an expression that contains at least one variable is known as an algebraic expression, and this type of expression is commonly used in algebra to represent mathematical relationships between variables. For example, "2x + 4" is an algebraic expression that contains the variable x and represents a linear equation in which y is equal to two times x plus four.
