Actually, there is
no specific problem or task stated in the image you uploaded.
The image is simply a
complete 20x20 multiplication chart, showing all products from 1×1 up to 20×20. It’s a reference tool — not a worksheet with questions to solve.

✔ What You *Can* Do With This Chart:
Since no problem was given, here are some common tasks students might be asked to do with such a chart — and how to solve them:
---
## 🎯 Example Task 1: “Find 7 × 8”
Solution:
- Locate row
7 (leftmost column).
- Locate column
8 (top row).
- Find where they intersect →
56
✔ Answer:
56
---
## 🎯 Example Task 2: “What is 15 × 12?”
Solution:
- Go to row
15.
- Go to column
12.
- Intersection =
180
✔ Answer:
180
---
## 🎯 Example Task 3: “List all multiples of 9 up to 20×9”
Solution:
- Look at row
9 (or column 9 — same result due to commutative property).
- Read across:
9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99, 108, 117, 126, 135, 144, 153, 162, 171, 180
✔ Answer: The multiples are as listed above.

## 🎯 Example Task 4: “Is 144 in the chart? If so, what multiplication pairs make it?”
Solution:
- Scan the chart for
144.
- Found at:
- 12 × 12
- 16 × 9
- 9 × 16
- 18 × 8
- 8 × 18
- 24 × 6 — but 24 isn’t on the chart (max is 20), so invalid.
- Also 36 × 4 — again, 36 > 20 → invalid.
✔ Valid pairs within 1–20:
→
12×12, 16×9, 9×16, 18×8, 8×18
---
## 🧠 Bonus Tip: Patterns in the Chart
-
Symmetry: The chart is symmetric along the diagonal (because `a × b = b × a`).
-
Diagonal: Contains perfect squares: 1, 4, 9, 16, ..., 400.
-
Even/Odd: Products follow parity rules — e.g., even × anything = even; odd × odd = odd.

❓ If You Meant to Ask Something Specific…
Please provide the actual question or task! For example:
> “What is 17 × 19?”
> “Circle all prime numbers in the chart.”
> “Find the product of the largest two numbers.”
I’d be happy to solve it for you!

✔ Final Note: Since no explicit problem was given, this chart itself is the *solution tool*. Use it to look up any multiplication fact from 1 to 20.
