Let’s solve this step by step.
We are given a grid of numbers from 1 to 100, arranged in 10 rows and 10 columns.
The task is not explicitly stated in your message — but since you uploaded the image and asked me to “solve the problem accurately,” I need to infer what the typical homework problem might be with such a grid.
Common problems with a 1–100 grid include:
- Finding patterns (like multiples, primes, even/odd)
- Adding or subtracting specific numbers
- Locating positions (e.g., “What number is in row 5, column 3?”)
- Counting how many numbers meet a condition
But since no specific question was written, let’s look at the most common type of problem associated with this exact grid:
“Find the sum of all numbers from 1 to 100.”
This is a classic math problem often taught using this kind of grid.

Step-by-step solution for: Sum of numbers from 1 to 100
There’s a famous trick attributed to Gauss:
Pair the first and last numbers:
→ 1 + 100 = 101
→ 2 + 99 = 101
→ 3 + 98 = 101
... and so on.
How many such pairs? Since there are 100 numbers, we can make 50 pairs.
So total sum = 50 × 101 = 5050
Let’s verify:
Formula for sum of first n natural numbers:
Sum = n(n+1)/2
Here, n = 100
→ Sum = 100 × 101 / 2 = 10100 / 2 =
5050
✔ Verified.

Final Answer:
5050
