These...solve problems involving powers of 2 explore the patterns to investigate 2 to the power of n and how it is written.
make meaning of 2 to the power of zero by patterning and dividing by 2 investigate combining powers of 2 and 3, and others like 5 use the x^y button on a calculator.
Multiplication and Division happen at the same time, from left to right.
Addition DOES NOT always get performed before Subtraction.
Solve addition and subtraction last after parentheses, exponents, roots and multiplying/dividing.
Again, proceed from left to right for adding and subtracting.Examples of left-associativity: For nested parentheses or brackets, solve the innermost parentheses or bracket expressions first and work toward the outermost parentheses.For each expression within parentheses, follow the rest of the PEMDAS order: First calculate exponents and radicals, then multiplication and division, and finally addition and subtraction.If your equation has fractional exponents or roots be sure to enclose the fractions in parentheses.For example: If you want an entry such as 1/2 to be treated as a fraction then enter it as (1/2).If you incorrectly enter it as 4/1/2 then it is solved 4/1 = 4 first then 4/2 = 2 last. PEMDAS is typcially expanded into the phrase, "Please Excuse My Dear Aunt Sally." The first letter of each word in the phrase creates the PEMDAS acronym.Solve math problems with the standard mathematical order of operations, working left to right: Multiplication DOES NOT always get performed before Division.For example, in the equation 4 divided by ½ you must enter it as 4/(1/2).Then the division 1/2 = 0.5 is performed first and 4/0.5 = 8 is performed last. PEMDAS is an acronym that may help you remember order of operations for solving math equations.The acronyms for order of operations mean you should solve equations in this order always working left to right in your equation.PEMDAS stands for "Parentheses, Exponents, Multiplication Subtraction" You may also see BEDMAS and BODMAS as order of operations acronyms.
