Subtraction Sign and Negative Sign/Negative Number Powers

Use the  key to enter a subtraction sign, and the  key to enter a negative

sign.

Example 1: To perform the calculation 10+8–3

K@(RUN • MAT)

@?GB

Actual solution: 15

Example 2: To perform the calculation –10+8–3

K@(RUN • MAT)

@?GB

Actual solution: –5

Example 3: To perform the calculation 10+8+(–3)

K@(RUN • MAT)

@?GB

Actual solution: 15

The above calculation also can be entered as shown below.

Differential and Integration Calculations

Example 1: If a ball is dropped from a height of 100 meters, how far will it have

fallen after three seconds?

• Use a 9.8 meters per second per second for gravitational

acceleration, and disregard air friction.

Perform the following calculation:



9.8xdx.

Select the integration function from the menu that appears when you

select {CALC} on the option (OPTN) menu.

Actual solution: 44.1 meters

This calculation can be verified using the formula

y =

, which yields

s 9.8 s 3

Example 2: If a ball is dropped from a height of 100 meters, at what speed will it

be traveling after three seconds?

• Use a 9.8 meters per second per second for gravitational

acceleration, and disregard air friction.

Use the expression

f(x)=

(

• 9.8x

) to calculate f(3).

Select the differential function from the menu that appears when you

select {CALC} on the option (OPTN) menu.
