Lab 1 (solution):
- Here is what you should have done:
  1. Start a new NeXtMidas session.
```
$ nmstart
```
  2. Start the NeXtMidas shell.
```
$ nm
```
  3. Set a result, X to 7.5.
```
nM> set x 7.5
```
  4. Compute the value of X multiplied by 3.5 and store the result in Y.
```
nM> calculator y x 3.5 *
```
  5. Now change the value of X to be 2.5.
```
nM> set x 2.5
```
  6. Compute the value of X multiplied by Y and store the result in hexadecimal notation in Z.
```
nM> calculator/hex z x y *
```
  7. What are the values of X, Y, and Z?
```
nM> get x
  D: X               = 2.5
nM> get y
  D: Y               = 26.25
nM> get z
10S: Z               = 0x00000034
```
