This exercise contains equations on both sides of the equal to sign. Each equation leads to a number which is the same. The caveat though is that one equation is missing a number, hence students have to find the missing number in order to make the equation balanced. The quiz is somewhat different

Learn to balance addition and subtraction equations

Addition and subtraction are two of the most basic mathematical operations, and they are also the building blocks of more complex math concepts. In this article, we will focus on how to use addition and subtraction to balance equations.

An equation is a statement that two things are equal. For example, 2 + 3 = 5 is an equation because 2 plus 3 is equal to 5. To balance an equation, we need to make sure that the equation is true by adjusting the numbers on one side of the equation to match the numbers on the other side.

One way to balance an equation is to use addition and subtraction to change the numbers on one side of the equation to match the numbers on the other side. For example, if we have the equation 2 + 3 = 5, we know that the equation is already balanced because 2 plus 3 is equal to 5.

However, if we have the equation 2 + 3 = 7, we can use addition to balance the equation by adding 2 to both sides of the equation. This gives us 2 + 3 + 2 = 7 + 2, which simplifies to 2 + 5 = 9. Now, the equation is balanced because 2 plus 5 is equal to 9.

Another way to balance an equation is to use subtraction to change the numbers on one side of the equation to match the numbers on the other side. For example, if we have the equation 5 – 2 = 3, we know that the equation is already balanced because 5 minus 2 is equal to 3.

However, if we have the equation 5 – 2 = 1, we can use subtraction to balance the equation by subtracting 2 from both sides of the equation. This gives us 5 – 2 – 2 = 1 – 2, which simplifies to 3 = -1. Now, the equation is not balanced, as its impossible that 3 equal -1, thus the original equation was incorrect.

It is important to note that when using addition and subtraction to balance equations, we need to make sure that we perform the same operation on both sides of the equation. This will ensure that the equation remains balanced. Also, while balancing equation is one thing, solving it another; it’s always important to have a clear understanding of what you are trying to find.

In summary, addition and subtraction are two of the most basic mathematical operations that we use to balance equations. We can use addition to increase the numbers on one side of an equation to match the numbers on the other side, and we can use subtraction to decrease the numbers on one side of an equation to match the numbers on the other side. By understanding how to use addition and subtraction to balance equations, children will be able to solve more complex math problems in the future.
