Q: Find the value of 9 × 9 - 5 × 5. (2019)
Solution:
9 × 9 = 81 and 5 × 5 = 25, so 81 - 25 = 56.
Steps: 4
Show Steps
Step 1: Calculate 9 times 9. This means you add 9 together 9 times: 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9 + 9. The answer is 81.
Step 2: Calculate 5 times 5. This means you add 5 together 5 times: 5 + 5 + 5 + 5 + 5. The answer is 25.
Step 3: Subtract the result of 5 times 5 from the result of 9 times 9. So, you take 81 and subtract 25 from it: 81 - 25.
Step 4: Perform the subtraction. 81 minus 25 equals 56.
