Multi-Step Addition and Subtraction Problems
1 Basic Multi-Step Problem
Problem 1: Tom had 15 apples. His mom gave him 8 more apples. Then he ate 6 apples. How many apples does Tom have now?
Definition:

Multi-step: Requires multiple operations (addition and subtraction)

Method:
  1. First: Add to find total apples received
  2. Second: Subtract the apples eaten
Step 1: Find total apples received
Tom starts with 15 apples
His mom gives him 8 more
15 + 8 = 23 apples total
Step 2: Subtract apples eaten
Tom eats 6 apples
23 - 6 = 17 apples remaining
15 + 8 - 6 = 17
Solution:
Tom has 17 apples now.
Final answer:

Tom has 17 apples now.

2 Intermediate Multi-Step Problem
Problem 2: A store had 45 books. They received 28 more books from the publisher. Then they sold 32 books. How many books are left in the store?
Step 1: Find total books after receiving more
Store had 45 books initially
Received 28 more books
45 + 28 = 73 books total
Step 2: Subtract books sold
Sold 32 books
73 - 32 = 41 books remaining
45 + 28 - 32 = 41
Solution:
There are 41 books left in the store.
Final answer:

There are 41 books left in the store.

3 Advanced Multi-Step Problem
Problem 3: A school bus picked up 24 students at the first stop. At the second stop, 18 more students got on. At the third stop, 15 students got off. How many students are on the bus now?
Step 1: Find total students after first stop
Bus picked up 24 students
24 students on the bus
Step 2: Add students from second stop
18 more students got on
24 + 18 = 42 students total
Step 3: Subtract students who got off
15 students got off
42 - 15 = 27 students remaining
24 + 18 - 15 = 27
Solution:
There are 27 students on the bus now.
Final answer:

There are 27 students on the bus now.

Addition and Subtraction Rules and Methods
Add → Increase, Subtract → Decrease
Operation Understanding
Key definitions:

Addition (+): Combining quantities to find a total

Subtraction (-): Taking away from a quantity

Keywords for Addition: more, added, increased, total, altogether, combined

Keywords for Subtraction: less, took away, decreased, remaining, left, difference

4-Step Problem Solving Method:
  1. READ: Carefully read the entire problem
  2. PLAN: Identify what operations are needed (addition/subtraction)
  3. SOLVE: Work through the problem step by step
  4. CHECK: Review your answer to ensure it makes sense
Tip 1: Circle key numbers and underline important words.
Tip 2: Draw pictures or diagrams to visualize the problem.
Tip 3: Write down each step to stay organized.
Tip 4: Check if your answer is reasonable.
Key insight: Addition increases the amount, subtraction decreases it.
Memory trick: "More" means add, "less" means subtract.
Essential rules:

• Always read the entire problem before starting

• Look for keywords that indicate operations (more, less, total, left)

• Solve one step at a time in order

• Check your answer makes sense in the context of the problem

• Show your work for each step

Questions & Answers

Question: How do I know when to add and when to subtract in a word problem?

Answer: Look for clue words in the problem:

  • Addition words: "more," "added," "total," "altogether," "combined," "increased"
  • Subtraction words: "less," "took away," "removed," "remaining," "left," "decreased"

Also think about the situation: if something is being gained, added, or combined, use addition. If something is being taken away, lost, or decreased, use subtraction.

Question: How can I help my child understand the difference between addition and subtraction in word problems?

Answer: Here are effective strategies:

  • Use physical objects to act out the problems
  • Practice identifying clue words together
  • Draw simple pictures to visualize the situation
  • Ask: "Are we getting more or losing some?"
  • Practice with simple problems before moving to multi-step ones

The key is helping your child visualize the situation and understand that addition combines quantities while subtraction takes away from quantities.
