Mastering Order of Operations with Integers

The video tutorial explains the order of operations using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. It covers the rules for handling each operation, including how to deal with signs in multiplication and division, and provides examples to illustrate these concepts. The tutorial emphasizes working from left to right and not skipping steps to ensure accurate results.

What does the 'P' in PEMDAS stand for?

• Parentheses

• Powers

• Products

• Primes

Which of the following is considered a grouping symbol?

• Multiplication

• Exponents

• Brackets

• Addition

If you have the expression 4^3, what does it mean?

• 4 divided by 3

• 4 multiplied by itself 3 times

• 4 added to 3

• 4 multiplied by 3

When multiplying two numbers with opposite signs, the result will be:

• Positive

• Negative

• Zero

• Undefined

When adding two numbers with the same sign, you should:

• Subtract them

• Divide them

• Add them and keep the original sign

• Multiply them
