1. **State the problem:** Multiply the two double-digit numbers in the first cell: $26 \times 62$. 2. **Formula:** Multiplication of two numbers is repeated addition. Here, we multiply each digit and add the partial products. 3. **Step-by-step multiplication:** $$ 26 \times 62 = 26 \times (60 + 2) = 26 \times 60 + 26 \times 2 $$ $$ = 1560 + 52 = 1612 $$ 4. **Final answer:** $26 \times 62 = 1612$ This is the first problem in the grid. Since the user asked to solve, we provide the solution for the first problem only as per instructions.
