Write an expression for the sequence of operations described below: c fewer than the difference of d and 9. Do not simplify any part of the expression.
Understand the Problem
The question is asking to formulate a mathematical expression representing 'c fewer than the difference of d and 9'. This involves finding the difference between d and 9, then subtracting c from that difference.
Answer
$$(d - 9) - c$$
Answer for screen readers
The expression representing 'c fewer than the difference of d and 9' is:
$$(d - 9) - c$$
Steps to Solve
- Identify the difference between d and 9
The first part of the expression requires finding the difference between $d$ and 9, which can be represented as:
$$ d - 9 $$
- Subtract c from the difference
Next, we need to represent 'c fewer than' the difference we just calculated. This means we will subtract $c$ from the difference:
$$ (d - 9) - c $$
- Final expression
The complete expression representing 'c fewer than the difference of d and 9' is:
$$ (d - 9) - c $$
The expression representing 'c fewer than the difference of d and 9' is:
$$(d - 9) - c$$
More Information
This expression captures the sequence of operations accurately. The difference between two values, $d$ and 9, is calculated first, and then $c$ is subtracted from that difference to reflect the phrase 'c fewer than'.
Tips
- Forgetting to account for the order of operations. Ensure you first find the difference before subtracting $c$.
- Misinterpreting 'fewer than' as an addition instead of a subtraction.
