Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
let the no. be 'x' therefore, the expression of 5 less than a no. is, x-5

Remember,an expression is a problem without an answer.If it's a 4 less than a number,it should be 4<x.Hope this helps your problems!
Subject: Algebra Topic: Expression Evaluation Step 1: Let the number be represented by the variable ( x ). Step 2: Write the expression for "a square of a number": ( x^2 ). Step 3: Write the expression for "3 less than a square of a number": ( x^2 - 3 ). Step 4: Provide the final answer: The expression representing "3 less than a square of a number" is ( x^2 - 3 ). Explanation: The expression ( x^2 - 3 ) represents the result of subtracting 3 from the square of a given number ( x ).
2x^2 - 1
x^2 - 7

7 less than a number is an algebraic expression. Given the number the expression can be evaluated. 7 is less than a number is a statement in the form of an inequality. It is true for some values of the number and not for others.
It means that the number or expression on the left of the symbol is less that the value or expression to the right, or that they are equal.
let the no. be 'x' therefore, the expression of 5 less than a no. is, x-5
4<x
