Certainly! Let's use each of the four operations—addition, subtraction, multiplication, and division—to set up and solve some real-world problems.
Addition Problem
Scenario: Sarah has 275 stickers, and her friend gives her 148 more stickers. How many stickers does Sarah have now?
Solution: \[ 275 + 148 = 423 \]
Sarah now has 423 stickers.
Subtraction Problem
Scenario: Carlos had 520 marbles. He gave away 178 marbles to his friends. How many marbles does Carlos have left?
Solution: \[ 520 - 178 = 342 \]
Carlos has 342 marbles left.
Multiplication Problem
Scenario: A box contains 24 chocolates. If there are 15 boxes, how many chocolates are there in total?
Solution: \[ 24 \times 15 = 360 \]
There are 360 chocolates in total.
Division Problem
Scenario: A farmer has 840 apples and wants to pack them into boxes that can each hold 28 apples. How many boxes can he fill?
Solution: \[ 840 \div 28 = 30 \]
The farmer can fill 30 boxes.
