Worked Example

Step-by-Step

Let's find 8 × 8 by repeated addition: --- Step 1: Start with the first 8. --- Step 2: Add another 8: 8 + 8 = 16. --- Step 3: Add another 8: 16 + 8 = 24. --- Step 4: Add another 8: 24 + 8 = 32. --- Step 5: Add another 8: 32 + 8 = 40. --- Step 6: Add another 8: 40 + 8 = 48. --- Step 7: Add another 8: 48 + 8 = 56. --- Step 8: Add the final 8: 56 + 8 = 64. So, 8 × 8 = 64.

Why It Matters

Understanding multiplication facts like 8 × 8 is crucial for many advanced topics. In computing, this number 64 is special because it's 2 raised to the power of 6 (2^6), which is fundamental in how computers store data. Engineers and data scientists use these concepts daily.
