List — find the minimum
Separate values with commas, semicolons or new lines.
Minimum Summary
Breakdown
| Property | Value |

| Sorted ascending | 2, 3, 5, 7, 9 |
| Range (max − min) | 7 |
Results
Minimum
2
Smallest value in the list
5
How many values were compared
2, 3, 5, 7, 9
Ascending order — minimum lands first
9
Largest value — frames the spread
The minimum is the first value of the ascending-sorted list, verified against every entry.

Formula
The minimum is the value no other value beats. Sorting makes it positional: first ascending wins.
Alternative Form
Variables
| Symbol | Name | Unit | Description |
|---|---|---|---|
| list | Values | numbers | All entered values |
| sorted | Ordered values | numbers | Ascending arrangement |
| min | Minimum | number | First of the sorted list |
| count | Sample size | count | How many values competed |
Explanation
Comparison is transitive: the survivor of pairwise contests is smaller than everything it beat.
Derivation
Pairwise min(a,b) returns the smaller; folding it across the list keeps an invariant (holder ≤ all seen). Sorting generalises the same comparisons into full order, so sorted[0] equals the fold — the global minimum.
Step-by-Step Calculation
Follow each step to understand how the result is calculated from your inputs.
Split the input into 5 separate numbers.
Sort the values from smallest to largest.
Take the first value of the sorted list — that is the minimum.
Verify: the minimum is less than or equal to every other value.
State the answer with its position in the list.
Worked Examples
See how the calculator works with different scenarios.
Scenario
Find the smallest of five.
Inputs
Calculation
Sorted: 2, 3, 5, 7, 9 — first is 2
Result
2
Interpretation
Sorting surfaces the minimum.
Understanding Your Result
Your Result: Minimum: 2
Typical range: Small integer lists first, then decimals, negatives and long datasets.
What This Means
The headline minimum is the lowest value you entered — the floor of your data.
Why It Matters
Record lows, price floors, minimum requirements and worst cases all start at the minimum.
Professional Interpretation
Pair the minimum with the range: a lone low value may be an outlier, not the story.
Recommendations
- •Scan for typos before trusting extremes
- •Compare min against the second-smallest
- •Keep units consistent
- •Sort to see the full shape
Learn — The Complete Guide
Minimum hunting is organised comparison: line values up, sort them, crown the first.
The core concept
Order the data ascending; position zero holds the minimum. Ties share the crown; entry order never matters.
- Sort ascending — first wins
- Ties share the minimum
- Negatives beat zero and positives
Derivations — why the formulas work
Fold equals sorted-first
- 1Holder starts at first value
- 2Each contest keeps the smaller ✓
- 3Holder ≤ everything seen, always
- 4Exhaustion leaves the global min ✓
Pairwise formula
- 1min(a,b) = (a+b−|a−b|)/2
- 2If a ≤ b: |a−b| = b−a, gives a ✓
- 3Symmetric, so order-free ✓
- 4Fold across lists for any size

2 is the default demo’s hero
In 3, 7, 2, 9, 5 the minimum hides mid-list — exactly why we sort instead of eyeballing.
Compare Side by Side
Minimum anchors the bottom of the spread — range and maximum frame the rest.
