We are now fully into the Order of Operations and will remain there for a time. We started out simple with a problem like 3+3 + (7 x 3) -4. Yesterday they learned the acronym GEMA.
G - grouping such as parentheses, brackets, and braces
E - exponents
M - multiply and divide
A - add and subtract
If there are instances of multiplying and dividing or adding and subtracting, one moves from left to right.
We gradually added more complex problems involving exponents.
