### How many days are in an ideal year?

• A.

230 days

• B.

In the order of mathematical operations, brackets come first. This is because brackets indicate that the operations inside them should be performed first before any other operation. This is known as the "order of operations" or "PEMDAS" (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction). So, when solving an expression or equation, any operations inside brackets should be done first, followed by any exponents, then multiplication and division, and finally addition and subtraction.
