Basic Operations

✨ Section 1: What Are Basic Operations?

In math, we use operations to work with numbers.
The two most important operations in Grade 1 are:

• ➕ Addition — putting numbers together
  
  

• ➖ Subtraction — taking numbers away
  
  

These are the first tools we use to solve problems in math!

🔢 Section 2: What Is Addition?

Addition means we are putting two or more groups together to find the total.

🧠 We use the plus sign + to show addition.

💡 Example:

• You have 3 apples 🍎
  
  

• You get 2 more 🍎🍎
  
  

• Total: 3 + 2 = 5
  
  

🧩 That’s addition! We’re joining numbers to make a bigger number.

➖ Section 3: What Is Subtraction?

Subtraction means we are taking away from a group.

🧠 We use the minus sign – to show subtraction.

💡 Example:

• You have 5 bananas 🍌🍌🍌🍌🍌
  
  

• You give away 2 🍌🍌
  
  

• What’s left? 5 – 2 = 3
  
  

🧩 That’s subtraction! We are removing part of the group.

🧠 Section 4: Why Are These Operations Important?

Addition and subtraction help us:

• Count things in the real world
  
  

• Share and give fairly
  
  

• Solve story problems
  
  

• Understand how numbers change
  
  

We use them every day — at the store, at home, at school!
