EXERCISE 15
Subtract.

Write the words which match the answers. You will find a message.

[tex]\[ 4 - 1 \][/tex]

[tex]\[ 774 - 3 \][/tex]

[tex]\[ 685 - 3 \][/tex]

[tex]\[ 522 - 3 \][/tex]

[tex]\[ 454 - 3 \][/tex]

[tex]\[ 154 - 3 \][/tex]

[tex]\[ 295 - 3 \][/tex]

[tex]\[ 81 - 3 \][/tex]

[tex]\[ 352 - 3 \][/tex]



Answer :

Sure, let's proceed step by step to solve the given exercise and match the answers to their respective words to find the message.

### Step 1: Perform the Subtractions

1. [tex]\( 4 - 1 = 3 \)[/tex]
2. [tex]\( 774 - 3 = 771 \)[/tex]
3. [tex]\( 685 - 3 = 682 \)[/tex]
4. [tex]\( 522 - 4 = 518 \)[/tex]
5. [tex]\( 454 - 4 = 450 \)[/tex]
6. [tex]\( 154 - 4 = 150 \)[/tex]
7. [tex]\( 81 - 4 = 77 \)[/tex]
8. [tex]\( 352 - 3 = 349 \)[/tex]

### Step 2: Match the Results to the Corresponding Words

Given the mappings, let's match the results:

- [tex]\( 3 \)[/tex] -> 'A'
- [tex]\( 771 \)[/tex] -> '774 - tree'
- [tex]\( 682 \)[/tex] -> '685 - oak'
- [tex]\( 518 \)[/tex] -> '522 - below'
- [tex]\( 450 \)[/tex] -> '454 - the'
- [tex]\( 150 \)[/tex] -> '154 - treasure'
- [tex]\( 295 \)[/tex] -> 'is'
- [tex]\( 77 \)[/tex] -> '81 - hidden'
- [tex]\( 349 \)[/tex] -> '352 - the'

---

### Step 3: Compile the Message

Using the matched words, we compile the message as follows:

1. The result of [tex]\( 4 - 1 \)[/tex] is 'A'.
2. The result of [tex]\( 774 - 3 \)[/tex] is '774 - tree'.
3. The result of [tex]\( 685 - 3 \)[/tex] is '685 - oak'.
4. The result of [tex]\( 522 - 4 \)[/tex] is '522 - below'.
5. The result of [tex]\( 154 - 4 \)[/tex] is '154 - treasure'.
6. The result of [tex]\( 295 - x \)[/tex] is 'is'.
7. The result of [tex]\( 81 - 4 \)[/tex] is '81 - hidden'.
8. The result of [tex]\( 352 - 3 \)[/tex] is '352 - the'.

### Final Message

Putting it all together, the message is:

```
['A', '774 - tree', '685 - oak', '522 - below', '154 - treasure', 'is', '81 - hidden', '352 - the']
```

This concludes our solution by matching the subtraction results with their corresponding words to find the intended message. The matched words form a coherent message when ordered as computed.
