Rachel said:When using PEMDAS it states that addition comes before subtraction.
Why is it that the 0 + 1 is not done first and then finally the 6 - 1 ?
That's the part that confuses me lol
The correct order of operations, also known as PEMDAS, is to first solve any parentheses or brackets, then exponents, followed by multiplication and division from left to right, and finally addition and subtraction from left to right.
This equation appears to have two different answers because of a common misconception about the order of operations. Many people incorrectly assume that multiplication should always be performed before division, leading them to solve the equation as 6-1x0+1=7. However, according to the correct order of operations, division should be performed before multiplication, resulting in the correct answer of 6-0+1=7.
Yes, this equation can be solved using a calculator as long as the calculator follows the correct order of operations. Most modern calculators are programmed to follow the order of operations, but it is always important to double check and use parentheses if necessary to ensure the correct answer.
In most mathematical equations, the order of operations must be followed to arrive at the correct answer. However, there are some specific cases, such as when using scientific notation or calculating with matrices, where the order of operations may differ slightly. In these cases, it is important to follow the specific rules for those operations.
Understanding the order of operations is an essential skill in many areas of life, such as cooking, budgeting, and organizing tasks. It allows us to perform multiple calculations in the correct order, leading to accurate results. It also helps us to solve problems efficiently and effectively, making it a valuable skill in both academic and real-world settings.
