According to the order of operations, since the exercise only involves addition operations, we will solve the problem from left to right:
Solve the following exercise:
\( 12+3\cdot0= \)
Zero is called the additive identity because adding it to any number leaves that number unchanged. Think of it like this: if you have half a pizza and add zero more pieces, you still have half a pizza!
No! Zero doesn't have a denominator, so you can simply ignore it in fraction addition problems. Focus on adding the actual fractions together.
When denominators are the same, just add the numerators and keep the same denominator:
With addition, you can work in any order because addition is commutative. However, working left to right is often clearest and follows the standard order of operations.
Always simplify! If your numerator and denominator have common factors, divide both by their greatest common factor. Here, because 2 ÷ 2 = 1.
