Order Of Operations With Negative Numbers Worksheet Pdf
Order of operations is a concept that is critical in the study of mathematics. It is a mathematical convention used to determine the order in which operations are to be performed in a mathematical expression. The order of operations is also referred to as PEMDAS, which stands for parentheses, exponents, multiplication, division, addition, and subtraction. It is essential to follow the order of operations to arrive at the correct answer.
Understanding Negative Numbers
Negative numbers are a fundamental concept in mathematics. They are numbers that are less than zero and are represented by a minus sign (-) before the number. Negative numbers are also commonly referred to as integers. To understand negative numbers, it is necessary to have a fundamental understanding of numbers and the number line. The number line is a graphical representation of all real numbers.
To locate negative numbers on the number line, we move to the left of zero. For example, -1 is one unit to the left of zero on the number line, and -5 is five units to the left of zero. Negative numbers can also be represented as fractions, decimals, or percentages.
Order of Operations with Negative Numbers
Order of operations must be followed when performing mathematical equations with negative numbers. The following is the order of operations:
- Parentheses must be solved first, and from the inside out.
- Exponents must be solved second.
- Multiplication and division must be solved from left to right.
- Addition and subtraction must be solved from left to right.
For example, consider the equation 4 - 5 x (-3) + 7. Following the order of operations, we first solve the multiplication inside the parentheses. Therefore, we have:
4 - 5 x (-3) + 7 = 4 + 15 + 7 = 26
Another example is the equation (-3)² x 2 + 5 x (-4). Following the order of operations, we first solve the exponent, then multiplication, then addition:
(-3)² x 2 + 5 x (-4) = 9 x 2 + (-20) = 18 - 20 = -2
