1. Price Comparison of Dress and Suit

The dress costs a rubles, and the suit costs b rubles. To find out how much cheaper the dress is compared to the suit, we can calculate the price difference by subtracting the cost of the dress from the cost of the suit: b - a = c.

2. Total Cost of Dress and Suit

The dress costs a rubles, and the suit costs b rubles. To calculate the total cost of the dress and suit together, we simply add the cost of the dress to the cost of the suit: a + b = d.

3. Price Difference and Total Cost

The dress costs a rubles, which is c rubles less than the cost of the suit. To find out the total cost of the dress and suit together, we can add the cost of the dress to the cost of the suit: a + b = d.

4. Money Remaining After Buying Ice Cream

If Petya has a rubles and Dima has b rubles, and they buy ice cream for c rubles, we can calculate the remaining money by subtracting the cost of the ice cream from the total amount of money they have: (a + b) - c = e.

5. Money Remaining After Buying Notebook and Pen

If Katya had m rubles and she bought a notebook for a rubles and a pen for b rubles, we can calculate the remaining money by subtracting the total cost of the notebook and pen from the initial amount of money she had: m - (a + b) = n.

6. Initial Amount of Money

If Vitya had x rubles and after buying a book for b rubles and an album for c rubles he had d rubles left, we can calculate the initial amount of money he had by adding the amount left to the total cost of the book and album: x = d + (b + c).
