# The Best Way to Answer Jamb Mathematics

The Best Way to Answer Jamb Mathematics- this is a tricky one, because there’s no much shut cut here for success apart from knowing the steps.

If you are writing maths in your JAMB CBT, this article will be very relevant to you since it has all the tips and tricks you need to know in answering JAMB CBT mathematics.

The better aspect of it is that you will be given calculator and rough sheets to do you mathematical calculation.

How is JAMB Mathematics?

JAMB CBT mathematics are simple problems that candidates are expected solve it with simple and sharp reasoning. You should be able to reason very fast and apply the mathematical rules when needed.

The main rules to adopt in JAMB maths in called Order of Operation. Order of operation are steps you need to adopt when working simple mathematical expressions. Another name for order of operation is BODMAS

## A. Use BODMAS

This is an aasy and simple way to remember BODMAS rule!!

B Brackets first (parentheses)

O Of (orders i.e. Powers and Square Roots, Cube Roots, etc.)

DM Division

Multiplication (start from left to right)

AS Addition and Subtraction (start from left to right)

Note:

(i) Start Divide/Multiply from left side to right side since they perform equally.

(ii) Start Add/Subtract from left side to right side since they perform equally

## B. Know the Formular

There are so many formulas in Mathematics. So, what you need to do is to have many of them in your head and learn how to apply them when needed.

My advice is that, you answer maths as your last subject in JAMB unless you trust yourself that you can deliver correct 40 questions out of 50.

## Be Attentive and Fast

It’s very important you are very attentive to the questions. Try and understand what the examiner wants from you in each question.  Of course, if you don’t quite know a particular question, move to the next one. You don’t need to score all to have the cut off mark for your school.
