Test: Subtraction - Grade 4 MCQ

When the minuend digit is smaller than the subtrahend, you must borrow from the next higher place value to perform the subtraction correctly.

When you borrow in subtraction, you decrease the higher place value by 1 and add 10 to the lower place value. For example, if you borrow 1 from the hundreds place, that hundreds digit decreases by 1.

Subtracting a number from itself results in zero. Therefore, 5,324 - 5,324 = 0.

Rounding 6,875 to 6,900 and 3,256 to 3,300 gives an estimated difference of 6,900 - 3,300 = 3,600.

The minuend is the number from which another number (the subtrahend) is subtracted in a subtraction problem.

To find the actual difference, you subtract the smaller number from the larger one directly, ensuring to follow the correct borrowing rules if necessary.

Performing the subtraction step by step gives: 9 - 9 = 0, 5 - 9 requires borrowing (making it 15 - 9 = 6), 5 - 4 = 1, and 4 - 3 = 1. Thus, 4,659 - 3,499 = 1,160.

The best way to frame a word problem is to present a scenario where you start with a total (minuend) and subtract what has been taken away (subtrahend), asking how much remains.

To find the difference, subtract each digit starting from the right: 8 - 3 = 5, 7 - 6 = 1, 9 - 2 = 7, and 4 - 3 = 1. Therefore, 4,978 - 3,263 = 1,715.

Subtracting 2,365 from 1,423 is not possible because 1,423 is less than 2,365, making it impossible to perform the operation without resulting in a negative number.

Subtracting 0 from any number leaves the number unchanged. For example, 5,324 - 0 = 5,324.

To find how many pairs are left, subtract the number sold from the total produced: 8,750 - 2,375 = 6,375.

First, add 1,129 and 5,372 to get 6,501. Then, add 4,013 and 215 to get 4,228. Finally, subtract 4,228 from 6,501 to get 2,273.

The expanded form of 7,439 is 7,000 + 400 + 30 + 9, which breaks down the number based on its place value.

The first step in subtracting with borrowing is to align the numbers properly in columns according to their place value. This alignment helps avoid mistakes in subtraction.
