There are infinite numbers that you can subtract to get **1**. In this tutorial, I will teach you how to find what minus what equals **1**. We will look at whole numbers decimals and Fractions

First, let’s look at the examples of the first 10 integers/whole numbers that will result to** ****1** when subtracted together

**1**** – 0 = ****1**

**2 ****– 1 = ****1**

**3 ****– 2 = ****1**

**4 – 3 = ****1**

**5 ****– 4 = ****1**

**6 – 5 = ****1**

**7 – 6 = ****1**

**8 – 7 = ****1**

**9 ****– 8 = ****1**

**10**** – 9 = ****1**

As you can see the list is endless as we can continue forever. Now let’s look at the fractions that you can subtract together to get **1**

**1 1/2 ****– 1/2 = ****1**

**1 1/5 ****– 1/5 = ****1**

**1 1/6– 1/6 = ****1**

As you can see above the fractions too are endless. Let’s look at the decimals that you can subtract together to get **1**

**1.50 ****– 0.50 = ****1**

**1.60 ****– 0.60 = ****1**

**1.70– 0.70 = ****1**
