Solve the following:
According to the order of operations, we must solve the exercise from left to right:
We'll also break down 8.8 into a smaller addition exercise that will be easier for us to calculate:
Now we'll use the commutative property since the exercise only involves addition.
Let's focus on the leftmost addition exercise, remembering that:
Next, we'll calculate the exercise below:
Finally, we are left with the following:
\( \text{0.6+0}.5= \)
The variable x stays the same because you're combining like terms. Think of it like: 2 apples + 3 apples = 5 apples. You add the quantities but keep the same type of object!
No need! Working with decimals directly is often easier and faster. Just be careful to line up decimal points when adding:
Add trailing zeros to make them the same length. For example, treat 0.2 as 0.20 and 8.6 as 8.60. This prevents alignment errors when adding.
Use estimation first: 0.2 + 8.6 + 0.65 is close to 0 + 9 + 1 = 10. Since 9.45 is close to 10, our answer makes sense!
Double-check your decimal alignment and addition. Common errors include misplacing decimal points or forgetting to carry over when adding columns.
