Test: Addition - Class 4 MCQ

Adding zero to any number does not change its value, meaning the sum remains the same as the original number.

To find the missing digit, you subtract the known number from the total: 11 - 4 = 7. Thus, the missing digit is 7.

To find the missing digit, you subtract the known addend from the total: 14 - 6 = 8. The missing digit is 8.

The first step in adding numbers without carry-over is to start from the ones place. This helps in neatly organizing the addition column by column, ensuring clarity in the calculation.

To find the total deposited on Wednesday and Friday, subtract Monday's deposit from the total: ₹10,411 - ₹4,550 = ₹5,861.

To find the total students, you would add the numbers together: 1,289 + 1,364 gives the total number of students in both schools.

The sum of the ones place is calculated as follows: 2 (from 4,532) + 8 (from 2,798) = 10. In this case, you write down 0 and carry over 1 to the tens place.

To find the third deposit, subtract the first two from the total: 10,411 - (4,550 + 2,765) = 10,411 - 7,315 = 3,096.

In expanded form, 5,798 is 5,000 + 700 + 90 + 8 and 3,543 is 3,000 + 500 + 40 + 3. Adding the thousands gives 5,000 + 3,000 = 8,000.

Adding zero to any number leaves the number unchanged, so 3,891 + 0 = 3,891.

If the known digit is larger than the total sum, you must account for a carry-over from the previous column to correctly calculate the missing digit.

To estimate, round 243 to 240, 1,654 to 1,650, and 2,285 to 2,290. Adding these rounded numbers gives 240 + 1,650 + 2,290 = 4,180.

The thousands digits are 6 (from 6,257) and 2 (from 2,384). Adding them gives 6 + 2 = 8.

Rounding both numbers gives 1,289 to 1,300 and 1,364 to 1,400. The estimated sum is 1,300 + 1,400 = 2,700.

Adding 1 to a number always results in the next consecutive number, illustrating the basic principle of counting.

The hundreds digits are 1 (from 3,123), 2 (from 1,242), and 3 (from 4,314). Adding them together gives 1 + 2 + 3 = 6.

Expanded form addition involves breaking down each number into its place values (thousands, hundreds, tens, ones) before performing the addition.

The associative property states that the way in which numbers are grouped in an addition problem does not affect the sum. This is shown in (2 + 3) + 4 = 2 + (3 + 4).

The commutative property of addition states that changing the order of the addends does not change the sum. For example, 7,460 + 321 equals the same as 321 + 7,460.

When the sum in a column is 10 or more, you write down the ones digit and carry over the tens digit to the next column. This ensures correct placement of values.
