According to the order of operations rules, we'll solve the exercise from left to right:
8.2
\( 0:7+1= \)
The order of operations says when you have only addition, work from left to right. This prevents mistakes and keeps your work organized!
You'd get 7.2, then add 1 to get 8.2 - which is still correct! Addition is commutative, but following left-to-right order helps avoid confusion.
Line up the decimal points! Think of 8 as 8.0, so . The whole number gets the decimal added to its ones place.
While calculators help check your work, practice doing simple decimal addition by hand first. It builds number sense and helps you catch calculator errors!
Keep going left to right! For example: becomes 8 + 0.2 + 3 = 8.2 + 3 = 11.2
