The basic rules for interpreting math expressions include the order of operations, which states that operations should be performed in a specific order (parentheses, exponents, multiplication/division, addition/subtraction), and the commutative and associative properties, which state that the order of numbers or variables does not change the result of an operation.
PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction, which is the acronym used to remember the order of operations.
Parentheses should be used to indicate which operations should be performed first in a math expression. They are also used to group terms together or to indicate multiplication when there is no symbol between two terms.
No, the order of operations should always be followed to ensure the correct result. Changing the order may lead to a different result.
When interpreting expressions with exponents, remember that the exponent represents the number of times the base is multiplied by itself. For example, 23 is equal to 2 x 2 x 2 = 8.
