EXPONENTS' OPERATIONS (MDAS)

Exponents operations also follow traditional mathematical operations. They are Multiplications, Divisions, Additions, and Subtractions, the most famous MDAS. It is by order or sequence MDAS was popularized. In a series of operations, Multiplication was the first, followed by, Division, Addition, and Subtraction. This is the same as elementary mathematics back in the old days. The only thing is that our term(s) used are made up of exponents. It is a term with literal base or numerical, with a number as expressions on the upper right corner. See below for illustrations;

Illustrations:

With the illustrations above, we are pretty sure that differences between bases vary. There are no permanent looks except for the general expression.

Illustrations:

Given that;

Notice that bases 3 and 2 have their own powers that tell how many they are. When extracted with the rule of MDAS, we found that the operation resulted in 11. Bear in mind that the expression does not limit to two or three. It is multiple with different operators. In (see below),

we can tell that it is an expression of three terms. Thus,

So, what if we have a subtraction operation?

Then,

Also,

Let's have a short practice with addition and subtraction operations.

Addition and Subtraction:

So we found out how addition and subtraction works in these exponent expressions. Let's have multiplication and division to complete our MDAS operation.

Given that;

for multiplication,
