Open a calculator page.
Type each of the following and press enter.

• $2+7$
• $2-7$
• $2\cdot7$
• $2÷7$
• $\displaystyle \frac{2}{7}$ (press ctrl then ÷ to enter fractions)

If the calculator returns a fraction, you can return a decimal approximation by:

• pressing ctrl then enter

Write $\displaystyle \frac{2}{7}$ correct to 6 decimal places: Check

Calculate the following:

• $-3-3$ (The first $-$ is negative (-). The second $-$ is subtract -)
• $-3-(-3)$
• $-3(-3)$
• $-3^2$
• $(-3)^2$
• $(-3)^3$ (^ for exponents)
• $\sqrt{3}$
• $\sqrt{-3} =$ Error: Non-real calculation
• $\sqrt[3]{3}$

Calculate to 6 significant figures: $\displaystyle\frac{-3-3^\frac{-3}{\sqrt{3}}}{\left(\sqrt[3]{3}\right)^{-3(-3)}}=$ Check

Calculate the following:

• $e^2=$ Check
• $\log_2{5}=$ Check
• $\ln{3}=$ Check

Other mathematical operations can be found by pressing Calculate the following:

• $\vert -4\vert=$ Check
• $\displaystyle\sum_{k=1}^5 k^2 =$ Check
• $\displaystyle\int_{1}^5 2x\; dx =$ Check

1. Enter $1+2$ then press enter
2. Type + $3$ then press enter
3. Type + $4$ then press enter
4. Type $1$ ÷ ctrl (-) then press enter
What was the result? Check

Calculate $\displaystyle\frac{6+\sqrt{(-6)^2-4(3)(2)}}{2(3)}=$ Check

To modify this calculation,

1. Press ▴ until you highlight $\displaystyle\frac{6+\sqrt{(-6)^2-4(3)(2)}}{2(3)}$, then press enter
2. Change the $+$ into a $-$ by pressing ◂, deleting $+$ and replacing it with $-$

Follow these steps to calculate $\displaystyle\frac{6-\sqrt{(-6)^2-4(3)(2)}}{2(3)}=$ Check

Let's say you want to find the value of the discriminant $(-6)^2-4(3)(2)$.

1. Press ▴ until you highlight $\displaystyle\frac{6-\sqrt{(-6)^2-4(3)(2)}}{2(3)}$
2. Press ◂ or ▸ until the cursor is inside the square root.
3. Hold ⇧shift and press ◂ or ▸ to highlight $(-6)^2-4(3)(2)$
4. Press enter.

The value of the discriminant $(-6)^2-4(3)(2)=$ Check

Just like with a computer, you can copy ctrl C and paste ctrl V

1. Type $1+$
2. Hold ⇧shift and press ◂ or ▸ to highlight $1+$
3. Copy by pressing ctrl C
4. Calculate $1+1+1+1+1+1+1+1+1+1$ by repeatedly pasting by pressing ctrl V.

To change between degrees and radians:

• Move the trackpad to RAD or DEG in the top right and click
or
• Press doc ▾ > 7 Settings & Status > 2 Document Settings... , then change Angle

Calculate $\sin^{-1} 0.3 =$ Check degrees or Check radians.
