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, =

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,=

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, =

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 6: π value:

To evaluate: 5 π

Enter as follows: 5, *, π

Enter as follows: 5, *, π

##### EXAMPLE 7: cuberoot():

To evaluate: cube root(3)

Enter as follows: 3,3√

Enter as follows: 3,3√

##### EXAMPLE 8: square root:

To evaluate: square root(4)

Enter as follows: 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, =

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

Enter as follows: 0, ex

##### EXAMPLE 11: 10x
