Solve Subtraction Problems with Missing Digits

Subtraction is an arithmetic operation that involves finding the difference between two numbers. However, when referring to subtraction on a missing number, it implies that one of the numbers involved in the subtraction is unknown or not given.

In this scenario, if you have a subtraction expression with a missing number, you can use algebraic techniques to solve for the unknown value. The objective is to determine the value that, when subtracted from a known number, yields the given result.

For example, 5 - 3 = 2, where 5 is the first number (the minuend), 3 is the second number (the subtrahend), and 2 is the result (the difference).

Examples of Subtraction Problems with Missing Digits

Problem 1: ____ - 8 = 36

Solution: To solve the equation "? - 8 = 36," we need to isolate the unknown value on one side of the equation.
To do this, we can add 8 to both sides of the equation to eliminate the -8 on the left side:? - 8 + 8 = 36 + 8

This simplifies to:? = 44

Therefore, the missing number in this equation is 44.

Problem 2: Find the missing numbers.

Solution: Let's fill in the missing digit, we can start by trying to subtract
7 – 3 = 4
9 – 1 = 8

Now 8 can’t be subtracted by 5 so we’ll borrow 1 from the previous number. Hence, 15 – 8 = 7
Since we have borrowed from the previous number so we need to add 1 on 5.
3 + 2 + 1 = 6

Therefore, the required solution is:

Problem 3: ____ - 7 = 22 + 13

Solution: To solve the equation "? - 7 = 22 + 13," we need to isolate the unknown value on one side of the equation.
To do this, we can add 7 to both sides of the equation to eliminate the -7 on the left side:
? - 7 + 7 = 22 + 13 + 7

This simplifies to:? = 42

Therefore, the missing number in this equation is 42.

Problem 4: Find ? by the correct digits.

Solution: Let's fill in the missing digit, we can start by trying to subtract 2 – 3 which can’t be solved so we’ll borrow 1 from 5.

Now, 12 – 3 = 9
After taking borrow 5 becomes 4 so,
4 – 0 = 4
8 – 1 = 7
6 - 5 = 1

Therefore, the required solution is:

Problem 5: ___ - 58 = 17

Solution: To solve the equation "? - 58 = 17," we need to isolate the unknown value on one side of the equation.
To do this, we can add 58 from both sides of the equation to eliminate the -58 on the left side:
? - 58 + 58 = 17 + 58

This simplifies to:
? = 75

Therefore, the missing number in this equation is 75.
