How do I **solve Jamb mathematics** without a scientific calculator since most of the questions require the use of a scientific calculator? This question shall be fully addressed in this article.

Like you may know, **Jamb doesn’t allow the use of a scientific calculator**. However, you will be given a basic calculator. This calculator is generally referred to as * Jamb calculator*.

The major drawbacks of the Jamb calculator in solving maths are as follows:

- It doesn’t have trigonometric functions like sine, cos and tan.
- It doesn’t have logarithmic and exponential functions.
- There are no integral and different functions in Jamb calculator.
- You cannot use it to solve advance surds.
- It is a single line calculator.

Now, you may be wondering how to solve the hot jamb topics above without the use of a **powerful** **calculator**. Let me show you the various ways to solve Jamb mathematics without the use of scientific calculator…

## How To Solve Jamb Trig Ratios Without Calculator

The only trig ratios that Jamb set in UTME examination are special angles. Special angles usually have standard values that you should know. You don’t need a calculator to attempt them.

For example, if you are required to find the value of Sin90° in Jamb, you don’t need to punch your calculator. Sin90° is a standard trigonometric function with standard answer. Simply, Sin90° = 1.

Simply, Sin90° = 1.

## How To Solve Jamb Logarithm Without Calculator

Jamb usually gives you the standard log values to use. All you need to do is simplify the expression and then substitute the standard logarithm values given.

The standard values are usually given after the questions. You would see something like; Take log10 = 1 and log15 = 1.1760912590556811. Hope you understand?

#### Properties of Logarithms

- log
_{a}1 = 0 because a^{0}= 1 - No matter what the base is, as long as it is legal, the log of 1 is always 0. That’s because logarithmic curves always pass through (1,0)
- log
_{a}a = 1 because a^{1}= a - Any value raised to the first power is that same value.
- log
_{a}a^{x}= x - The log base a of x and a to the x power are inverse functions. Whenever inverse functions are applied to each other, they inverse out, and you’re left with the argument, in this case, x.
- log
_{a}x = log_{a}y implies that x = y - If two logs with the same base are equal, then the arguments must be equal.
- log
_{a}x = log_{b}x implies that a = b - If two logarithms with the same argument are equal, then the bases must be equal.

## How To Solve Differentiation And Integration In Jamb Mathematics

Generally, Jamb differentiation and integration questions don’t require the use of calculator. You would be given questions as simple as ABC. E.g Integrate SinÎ˜. The calculus part of jamb maths is usually fun to solve.

**Conclusion:** It is true that Jamb doesn’t give out scientific calculator to candidates. However, you got all it takes to attempt all Jamb maths without Big calculators. The basic calculator given by Jamb is enough for you to score very high in Jamb mathematics.
