Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
80-27
3 - k
The expression is: x -15
No because -10 is less than -1
In algebra mathematical symbols are used to compare multiple quantities. The symbols are < and > which represent greater or less than depending on expression and = for equivalent. Another symbol of quantity comparison is less/greater than or equal to.
4n-5 (Which is four times a number minus 5)
They mean that the expression to the left of the sign is greater than or less than (as appropriate) the expression to the right of the sign.
You write it as5nNothing more, nothing less.
Subtract 25 from whatever variable you use for "a number". If your number is "x", then the expression becomes "x - 25".
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 ).

Re-write it with a root. If the power of the expression is less than 1, for example x1/3, the expression could be rewritten as cube root of x.
