4 (2)² − 10 ÷ 5 + 8. The next part of PEMDAS is exponents (and square roots). There is one exponent in this problem that squares the number 2 (i.e., what we found by simplifying the expression in the parentheses). This gives us 2 × 2 = 4. So now our equation looks like this: 4 (4) − 10 ÷ 5 + 8 OR 4 × 4 − 10 ÷ 5 + 8.

Jul 18, 2024 · Subtract 6 from 2. The order of operations is a set of rules that tells us what math operation to do first in an expression with multiple operations like addition, subtraction, multiplication, and division. Following the order of operations, when solving 3 + 8 × 2 - 6, we would first do the: Multiplication: 8 x 2 = 16, so we get 3 + 16 – 6.
Jan 7, 2021 · The PEMDAS rule is a popular memory tool for recalling the math order of operations. The rule stands for P: Parenthesis, E: Exponents, M: Multiplying, D: Dividing, A: Adding, S=Subtracting. In general, operations are performed from left to right, but there are very important key sub-rules, namely (1) perform multiplying/dividing from left to ...

As we discussed above Order of operations can be defined as, a set of basic rules of precedence we use while solving any mathematical expression, involving multiple operations. When a subexpression appears between two operators, the operator that comes first according to the list given below should be applied first. The order of operations, rules a...

If it isn't a number it is probably an operation. But, when you see something like ...
Step 1: Do as much as you can to simplify everything inside the parenthesis or grouping symbol. Step 2: Simplify exponential numbers in the numerical expression, wherever possible. Step 3: Multiply and divide whichever comes first, from left to right. Step 4: Add and subtract whichever comes first, from left to right.
