Comparing Expressions in 2nd Grade Math

To compare the values of the given expressions, let's evaluate each expression and compare the results.

1. 7x8 and 9x6: - Evaluating 7x8: 7 multiplied by 8 equals 56. - Evaluating 9x6: 9 multiplied by 6 equals 54. - Therefore, 7x8 is greater than 9x6. (56 > 54)

2. 8x9 and 9x8: - Evaluating 8x9: 8 multiplied by 9 equals 72. - Evaluating 9x8: 9 multiplied by 8 equals 72. - Therefore, 8x9 is equal to 9x8. (72 = 72)

3. 8x8 and 7x9: - Evaluating 8x8: 8 multiplied by 8 equals 64. - Evaluating 7x9: 7 multiplied by 9 equals 63. - Therefore, 8x8 is greater than 7x9. (64 > 63)

4. 8x8 and 9x9: - Evaluating 8x8: 8 multiplied by 8 equals 64. - Evaluating 9x9: 9 multiplied by 9 equals 81. - Therefore, 8x8 is less than 9x9. (64 < 81)

In summary, the results of the comparisons are as follows: - 7x8 > 9x6 - 8x9 = 9x8 - 8x8 > 7x9 - 8x8 < 9x9
