**HOW TO USE VIRTUAL SCIENTIFIC CALCULATOR HOW IT WORKS**

**EXAMPLE 1: Simple Arithmetic: Simply follow the sequence**

To evaluate: 50 + 45 x 3

Enter as follows: 50, +, 45, *, 3, =

To evaluate: 50 x 45-2

Enter as follows: 50, *, 45, -, 2, =

To evaluate: 25 x (5+5)

Enter as follows: 25, *, (, 5, +, 5, ), =

**EXAMPLE 2: To evaluate function(value), enter value followed by function**

To evaluate: 2 + log(20) x 5

Enter as follows: 20, log, *, 5, +, 2, =

To evaluate: log(30) x 5 - 7

Enter as follows: 30, log,*, 5, -, 7, =

To evaluate: In(25) x 2 + 5

Enter as follows: 25, In, *, 2, +, 5, =

To evaluate: 5 + In(25) x 2

Enter as follows: 25, In, *, 2, +, 5,=

**EXAMPLE 3: sin(Degree), cos(Degree), tan(Degree):**

Select Deg

To evaluate: sin(45) or cos(45) or tan(45)

Enter as follows: 45, sin or cos or tan

**To evaluate: tan(45) x 5 + 2**

Enter as follows: 45, tan, *, 5, +, 2, =

**EXAMPLE 4: yroot() value:**

To evaluate: 4th root of 5

Enter as follows: 5, y√x, 4, =

**EXAMPLE 5:cube() value:**

To evaluate: 563 x 6+8

Enter as follows:56, X3, *, 6, +, 8, =

**EXAMPLE 6: π value:**

To evaluate: 5 π

Enter as follows: 5, *, π

To evaluate: cube root(3)

Enter as follows: 3,3√

**EXAMPLE 8: square root:**

To evaluate: square root(4)

Enter as follows: 4,√

**EXAMPLE 9: factorial (nỊ)**

To evaluate: factorial(5)

Enter as follows: 5,

nỊ To evaluate: factorial(6)*5-2

Enter as follows: 6, nỊ, *, 5, -, 2, =

**EXAMPLE 10: exponential (ex)**

To evaluate: e0

Enter as follows: 0, ex

**EXAMPLE 11: 10x**

To evaluate: 102.5

Enter as follows: 2.5, 10x To evaluate: 10-0.509

Enter as follows: 10, ^, 0.509, +/-, =

To evaluate: 10-2
