##### When percentage (%), factorials (!), logarithms and trigonometric involve in BODMAS question. How we solve it? ____________________________________

In questions of order of operations (BODMAS/ PEMDAS) when percentage, logarithms, and trigonometric (sine, cosine and tangent similarly their reciprocals cosecant, secant, and cotangent) are involved how should we evaluate these kind of questions. Actually BODMAS or PEDMAS are not covered this topic. How we evaluate these kinds of questions.

Factorials, Percentage, logarithms, and trigonometric they are all function it means that you have to convert them into numbers before solving division, multiplication, addition or subtraction. Therefore solve the factorials, percentage, logarithms, and trigonometric just after the parenthesis.
The following example will cover this topic more clearly.

`Example 1 : 3log(10)*a^0`

This kind question may create confusion whether you should multiply or do the log and exponents first. In such kind questions you have to change "log(10)" and "a^0"into numbers. You have to know that log(10) = 1 and e^0 = 1. Therefore

= 3log(10)*a^0
= 3* 1 *1
= 3

`Example 2 : 2e × 100%`

In such kind questions you have to covert e and 100% change into numbers. You have to know that e = 2.72 approximate
and 100% = 1. Therefore

• What is "e"? • = 2 × 2.72 × 1
= 5.44

```Example 3 : 5Cos(pi) (-3^0)
```

Here you have to change Cos(pi) and -3^0 into numbers. You have to know that Cos(pi) = -1 and -3^0 = -1. Therefore

5Cos(pi) (-3^0)
= 5 (-1)(-1)
= 5
