1. The problem shows a 2x2 grid with numbers 7 and 9 in the top row, and numbers 48 and 105 below the grid. 2. The multiplication signs between 7 and 9 suggest we multiply these numbers: $7 \times 9 = 63$. 3. The numbers 63 and 80 are shown vertically to the right of the grid, and 63 matches the product of 7 and 9. 4. The number 48 is below the 7, and 105 is below the 9, suggesting a multiplication relationship with the bottom-left position. 5. Since the question asks for the sum at the bottom-left, we consider the product $7 \times 48$. 6. Calculate $7 \times 48$: $$7 \times 48 = 336$$ 7. Therefore, the sum or product at the bottom-left position is $336$. Final answer: $336$
