Maths for Diploma Studies
This lesson is designed to provide the background knowledge in maths required to study CIBD Diplomas successfully. It will describe the basics of maths before detailing the more complex concepts encountered in CIBD lessons. Techniques for working with numbers, equations, and units will also be described.
Order of Operations Reinforcement Questions
1.
Calculate the answer to this equation:
We have no parenthesis or exponents, so we start with multiplication and division:
We then move to addition and subtraction working from left to right:
2.
What is the answer to the equation below?
We begin with the operations in brackets following the order of division, multiplication, addition, and subtraction:
Now with the brackets sorted, we move to the exponents:
3.
What is the outcome of this equation?
This equation has every element of PEMDAS. Following the correct order, we begin with the bits in the brackets.
And then the calculation in the next set of brackets:
With that complete, we then move on to the exponents:
Then, we address the division and multiplication:
Finally, we do the addition and subtraction working from left to right:
4.
What is the value of x in the equation below?
As always, we start with the calculations in the brackets:
Then exponents:
Then multiplication:
Next division:
Finally, addition and subtraction:
5.
Complete the calculation below to find the value of a.
So it's parenthesis first:
Then we resolve the next set of parentheses (brackets):
Then the division as that’s closest to the left:
Then multiplication:
Finally addition:
Now it’s time for everyone’s favourite part of maths, equations!
