Understanding 99 - 88 in the Context of Basic Arithmetic Operations

In the realm of basic arithmetic, understanding and solving expressions is a fundamental skill. One such expression that often puzzles learners is 99 - 88, which is frequently mistaken for 9 x 9 - 8 x 8. Let's delve into the correct way to solve this expression and explore the proper sequence of operations.

Breaking Down the Expression

When we encounter the expression 99 - 88, it (9 x 9 - 8 x 8) is often misinterpreted due to a lack of clarity in the order of operations. To solve this problem accurately, we need to break it down into manageable steps.

Step 1: Solving 9 x 9

First, we calculate the product of 9 and 9.

9 x 9 81

Step 2: Solving 8 x 8

Next, we calculate the product of 8 and 8.

8 x 8 64

Step 3: Combining the Results

Now that we have obtained the results from the two individual multiplications, we need to combine them according to the original expression. In this case, the original expression seems to be 99 - 88, which is not the same as 9 x 9 - 8 x 8. Let's address the original expression first.

To solve 99 - 88, we perform the subtraction directly.

99 - 88 11

Correct Interpretation

However, if we were to solve 9 x 9 - 8 x 8 as intended, we would follow the steps outlined above. Let's re-evaluate the expression with the correct operations.

Step 4: Solving 9 x 9 - 8 x 8

First, we calculate:

9 x 9 81

8 x 8 64

Then, we subtract:

81 - 64 17

Conclusion

The correct answer to the expression 9 x 9 - 8 x 8 is 17. It is crucial to follow the proper order of operations and understand the context in which math expressions are presented.
