Section 1: Basic Addition and Subtraction
1 Basic Addition
Problem 1
24 + 17 = ?
Definition:

Addition: Combining two or more numbers to find their total.

Addition method:
  1. Add the ones place: 4 + 7 = 11
  2. Regroup: 1 ten and 1 one
  3. Add the tens place: 2 + 1 + 1 = 4
  4. Combine: 4 tens and 1 one = 41
Problem
24 + 17
Work
24 + 17 = 41
Answer
41
Step 1: Add ones place

4 + 7 = 11, write down 1 and carry 1 to tens

Step 2: Add tens place

2 + 1 + 1 (carried) = 4

Step 3: Combine results

4 tens and 1 one = 41

24 + 17 = 41
Final answer:

24 + 17 = 41

Applied rules:

• Regrouping: When sum ≥ 10, carry to next place

• Place Value: Keep digits in correct columns

• Checking: 41 - 17 = 24 to verify

2 Basic Subtraction
Problem 2
52 - 28 = ?
Definition:

Subtraction: Finding the difference between two numbers.

Problem
52 - 28
Work
52 - 28 = 24
Answer
24
Step 1: Try to subtract ones

2 - 8 cannot be done, so borrow from tens

Step 2: Regroup

52 becomes 4 tens and 12 ones

Step 3: Subtract

12 - 8 = 4, 4 - 2 = 2

52 - 28 = 24
Final answer:

52 - 28 = 24

Applied rules:

• Borrowing: When top number < bottom number

• Regrouping: 1 ten = 10 ones

• Checking: 24 + 28 = 52 to verify

3 Mixed Operations
Problem 3
35 + 19 - 14 = ?
Definition:

Mixed Operations: Problems containing both addition and subtraction.

Problem
35 + 19 - 14
Work
54 - 14 = 40
Answer
40
Step 1: Perform addition first

35 + 19 = 54

Step 2: Then perform subtraction

54 - 14 = 40

Step 3: State final answer

35 + 19 - 14 = 40

35 + 19 - 14 = 40
Final answer:

35 + 19 - 14 = 40

Applied rules:

• Order of Operations: Work left to right

• Addition First: 35 + 19 = 54

• Then Subtraction: 54 - 14 = 40

Section 2: Advanced Problems
4 Word Problem
Problem 4
Sarah had 85 stickers. She gave 23 to her friend and bought 37 more. How many stickers does she have now?
Definition:

Word Problem: Real-life situation requiring mathematical operations to solve.

Problem-solving method:
  1. Read the problem carefully
  2. Identify what is being asked
  3. Determine which operations to use
  4. Solve step by step
  5. Check your answer
Starting
85 stickers
Operations
-23, +37
Answer
99 stickers
Step 1: Identify starting amount

Sarah started with 85 stickers

Step 2: Subtract what was given away

85 - 23 = 62 stickers remaining

Step 3: Add what was bought

62 + 37 = 99 stickers total

Sarah has 99 stickers now
Final answer:

Sarah has 99 stickers now.

Applied rules:

• Key Words: "gave" means subtract, "bought" means add

• Multi-step: Solve one operation at a time

• Context: Answer makes sense in the story

5 Multi-Digit Addition
Problem 5
124 + 358 = ?
Definition:

Multi-digit Addition: Adding numbers with multiple place values.

Problem
124 + 358
Work
482
Answer
482
Step 1: Add ones place

4 + 8 = 12, write down 2, carry 1

Step 2: Add tens place

2 + 5 + 1 (carried) = 8

Step 3: Add hundreds place

1 + 3 = 4

124 + 358 = 482
Final answer:

124 + 358 = 482

Applied rules:

• Column Addition: Add digits in same place value

• Regrouping: Carry when sum ≥ 10

• Place Value: Keep digits aligned by place

Tip 1: Always align numbers by place value when adding or subtracting.
Tip 2: Check your work by using the inverse operation.
Tip 3: For word problems, underline key information.
Tip 4: Estimate first to check if your answer is reasonable.
Scoring Guide:

Excellent (5/5): All problems solved correctly with clear work shown.

Good (4/5): 4 problems correct with minor computational errors.

Fair (3/5): 3 problems correct, needs review of regrouping.

Needs Work (≤2/5): Requires additional practice with basic facts.
