Order of Operations
Write and interpret numerical expressions.
OA.1 Use parentheses, brackets, or braces in numerical expressions, and evaluate expressions with these symbols.
OA.2 Write simple expressions that record calculations with numbers, and interpret numerical expressions without evaluating them. For example, express the calculation “add 8 and 7, then multiply by 2” as 2 × (8 + 7). Recognize that 3 × (18932 + 921) is three times as large as 18932 + 921, without having to calculate the indicated sum or product.
Analyze patterns and relationships.
OA.3 Generate two numerical patterns using two given rules. Identify apparent relationships between corresponding terms. Form ordered pairs consisting of corresponding terms from the two patterns, and graph the ordered pairs on a coordinate plane. For example, given the rule “Add 3” and the starting number 0, and given the rule “Add 6” and the starting number 0, generate terms in the resulting sequences, and observe that the terms in one sequence are twice the corresponding terms in the other sequence. Explain informally why this is so.
Perform operations with multi-digit whole numbers and with decimals to hundredths.
NBT.7 Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.

Brackets and Braces
When an order of operations problem has brackets and/or braces, what do you do?
Just like a problem that parentheses, you solve everything inside it FIRST.
Look at the example below.
You have to solve everything inside the braces first. The braces are the curly bars in the problem below.
BUT I have to do what is inside the bracket before I can add 1.
BUT before I can multiply by 4 and add 3, I have to do what is in the parentheses first.
The brackets and braces basically tell you that everything inside MUST be done before you can do the things outside of it.
