Use the calculator below to find what you can subtract** X** to get **Y**. This calculator will help you solve step by step the equation where you already have two numbers but need to find the last one to make it complete.

**What is minus?**

Minus simply means to subtract. It is also called, subtraction, subduction, difference, deduction, withhold, decrease, take, diminish and detract.

**Parts of Subtraction**

Every subtraction problem is made up of 3 parts. The parts include; minuend, subtrahend, difference, minus sign and equal sign.

**X – Y = Z**

X: Minuend

Y: Subtrahend

Z: Difference

-: Minus symbol

=: Equals symbol

**How to solve what minus X equals Z**

**Step 1:** Form the Equation

A – X = Z

**Step 2:** Add X on both Sides

A – X + X = Z + X

**Step 3:** Simplify the equation

A = Z+ X

Let us look at how to solve X minus Y using examples

**Example 1: What minus 200 equals 50? **

**Step 1: **A – 200 = 50

**Step 2:** A- 200 + 200 = 50 +200

**Step 3: **A =50 + 200

**Step 4: **A = 250

Therefore 250 minus 200 equals 50

**Example 2: What minus 10 equals 42? **

**Step 1: **A- 10 = 42

**Step2: **A- 10 + 10 = 42 +10

**Step 3: **A = 42 +10

**Step 4: **A = 52

Therefore 52 minus 10 Equals 42

**Example 3: What minus 149 equals 280? **

Step 1: A – 149 = 280

Step 2: A – 149 + 149 =280 +149

Step 3: A = 280 + 149

Step 4: A = 429
