How to Tell If a Subtraction Equation Is True or False

      True means correct or right. ✅

      False means wrong or not correct. ❎

False is the opposite of true. If something is true, it's not false.

      Subtraction is taking away from a number.

      A subtraction equation shows subtraction using minus and equal signs.

Let's learn how to tell if a subtraction equation is true or false.

True or False?

Here's a subtraction equation:

3 - 2 = 1

      The equal sign means what's on the left should be the same as what's on the right.

To decide if an equation is true or false, we look at both sides.

      An equation is true if both sides have the same value.

One side says "3 - 2". The other side says "1".

We know that:

3 - 2 is 1

and

1 is equal to 1

✅ So, this equation is true!  

Both sides have the same value, 1.

Another Example

Is this equation true or false?

4 - 1 = 2

Just follow the same steps!

👉 First, look at both sides.

We know that:

4 - 1 is 3

but

3 is not equal to 2

❎ This equation is false!  

The two sides are not the same.

Let's try one more example:

5 - 1 = 7 - 3

Start by looking at both sides.

The left side shows 5 - 1.

5 - 1 = 4

The right side shows 7 - 3.

7 - 3 = 4

4 equals 4!

✅ This equation is true!

The two sides have the same value.

Great work!
