Break Down the Algebraic Expression: Understanding 5m

Q: Why is there no plus or times sign between 5 and m?

In algebra, when a number sits directly next to a variable with no space, it automatically means multiplication! Writing $ 5 \times m $ every time would be too cluttered, so $ 5m $ is the shorthand.

Q: Is 5m the same as m5?

Yes! Multiplication is commutative, so $ 5m = m \cdot 5 = m5 $. However, we always write the number first by convention, so $ 5m $ is the proper form.

Q: What's the difference between 5m and 5 + m?

$ 5m $ means 5 times m (multiplication)$ 5 + m $ means 5 plus m (addition)These give completely different results! If $ m = 3 $: $ 5m = 15 $ but $ 5 + m = 8 $.

Q: How do I know what operation to use when there's no symbol?

When there's no symbol between a number and variable, it's always multiplication! This is a fundamental rule in algebra that never changes.

Q: Can I write 5m as 5 × m in my answer?

Technically yes, but $ 5 \cdot m $ with the dot is preferred in algebra. The × symbol can be confused with the variable x, so mathematicians use the dot or no symbol at all.

Follow each step carefully to understand the complete solution

Understand the problem

Break down the expression into basic terms:

$5m$

Step-by-step solution

To break down the expression $5m$ , we recognize it as the product of $5$ and $m$ :

$5m = 5 \cdot m$

This expression can be seen as a multiplication of the constant $5$ and the variable $m$ .

Final Answer

$5\cdot m$

Key Points to Remember

Essential concepts to master this topic

Multiplication Rule: Numbers next to variables mean multiply: $5m = 5 \cdot m$
Technique: When coefficient and variable touch, insert multiplication symbol between them
Check: Verify by substituting: if $m = 3$ , then $5m = 5 \cdot 3 = 15$ ✓

Common Mistakes

Avoid these frequent errors

Confusing multiplication with addition
Don't write $5m$ as $m + 5$ = wrong operation! When a number sits directly next to a variable with no space or symbol, it always means multiplication. Always remember that $5m = 5 \times m$ , not addition.
