What is the answer to 3-3x6+2=

Answers

The answer to the given expression 3 - 3 × 6 + 2is -13. This expression is simplified using the concepts of PEMDAS.

In mathematics, an expression is a combination of numbers, variables, and operators that represents a mathematical value.

An expression consists of letters or numbers and mathematical operations.

For instance, the following expression: "2 + 3" is a mathematical expression that represents the value 5.

The operations are ordered as follows:

Parentheses
Exponents
Multiplication and Division
Addition and Subtraction

According to PEMDAS, first, the numbers inside the parentheses are operated, and then the exponential function is solved. Then after, multiplication took place, followed by division, addition, and at last subtraction.

$3 -3* 6 +2 = 3 - 18 + 2$

$= - 13$ .

Hence, we conclude that the answer to the above expression is -13.

8.88 x 10,000 really confused with this one on my homework, can you guys anseer and explain why? would really help!

Answers

When multiplying by a number that is 1 with 0's on the end, you move the decimal to the right by how many zeros there are.

Because 10,000 has 5 0's, we move the decimal 5 places to the right.

8.88 => 88800
