Which calculation will yield the largest value: 10 x 10, 100 ÷ 4, or 5 x 20?

Calculating each expression helps to identify which one yields the largest value.

First, evaluating 10 x 10 results in 100.

Next, the calculation of 100 ÷ 4 yields 25.

Finally, when calculating 5 x 20, the result is also 100.

Comparing these results: 10 x 10 and 5 x 20 both equal 100, which is greater than 100 ÷ 4, which equals 25.

Thus, the two expressions that produce the highest value are 10 x 10 and 5 x 20, as both yield 100, which is significantly larger than 25 from the division. The answer should focus on the calculated results revealing that options A and C both give the same maximum value.
