When you travel, it’s important to keep track of your expenses. Here are some basic math skills you’ll need:

1. Addition: This is when you add up all your different costs.

   Things like:

   • Fuel ($F$)
   • Accommodation ($A$)
   • Food ($D$)

   You can find your total expenses by adding them together like this: $\text{Total Expenses} = F + A + D$

2. Subtraction: Sometimes, you might get money back or have discounts.

   In that case, you will need to subtract to find out how much you really spent.

   For example, if your total cost was $500$ and you received $100 back: $\text{Net Cost} = 500 - 100 = 400$

3. Multiplication: This comes in handy when you need to calculate costs for each unit.

   For example, if a hotel costs $80$ per night and you stay for $3$ nights, you would multiply: $\text{Hotel Cost} = 80 \times 3 = 240$

Knowing how to use these math operations will help you plan your budget and manage your money better when you travel!
