Test: Addition - Grade 4 MCQ

The first step in solving a word problem is to read it carefully and identify the numbers and what they represent to determine the correct operation needed.

In 57 + 19, the ones digits add to 16 (7 + 9), which requires carrying over. The final sum will be 76.

Adding the ones: 5 + 7 = 12 (write 2, carry 1). Adding the tens: 4 + 6 + 1 = 11. So, the total is 112.

Breaking the numbers into tens and ones, 30 + 20 = 50 and 4 + 5 = 9, gives 50 + 9 = 59.

Adding 0 to any number results in the original number; hence, 356 + 0 = 356.

Expanded form: 61 = 60 + 1 and 28 = 20 + 8. Adding tens: 60 + 20 = 80 and ones: 1 + 8 = 9 gives you 80 + 9 = 89.

Rounding 52 to 50 and 19 to 20 gives an estimated sum of 50 + 20 = 70.

Rounding 36 to 40 and 27 to 30 gives an estimated sum of 40 + 30 = 70, which helps in verifying the actual addition.

Adding 5 + 5 equals 10. Therefore, you would have 10 pencils.

Adding the ones: 8 + 7 = 15 (write 5, carry over 1). Adding the tens: 5 + 3 + 1 (carried over) = 9. Thus, the total is 95.

When the sum of the ones digits exceeds 9, like in 27 + 38 (7 + 8 = 15), you write down 5 and carry over 1 to the tens place to add to the next digits.

To add 23 and 45, align the numbers by place value. Adding the ones: 3 + 5 = 8, and adding the tens: 2 + 4 = 6. Thus, the final answer is 68.

Adding these three numbers gives 857. You can add them in steps to ensure accuracy.

The identity property of addition states that when zero is added to any number, the sum remains the same.

Adding 256, 232, and 208 gives 696. You add each group to find the total.
