🪄如何巧妙地計算除法呢 ？

方法 1 - 簡化：Simplify before you start ⚡

意思係先約簡數字，把數字變細了，看落去便更加容易了，亦有效減少錯誤 e.g.所有雙數

方法 2 - 倍大：Multiply before dividing 🔦

依據 Base 10 的原理，我們把數字倍大成一個 10 Facts，便能把整個運作來得更順暢了 e.g. 5, 25

方法 3 - Split the divisor 🫲

我們可以把 Divisor 分拆，令到整個算式變得更簡潔，Divisor 拆細了亦利於加快思考速度

🎀拆解數字不但可以應用到除法，加法或乘法也可以有效運用呢

例如：
18 x 7

把 18 拆成 2 x 9

再重新排列算式 7 x 9 x 2
= 63 x 2
= 126

🪄 How to Master Division with Simple Tricks?
Method 1 - Simplify First ⚡
Before diving into division, simplify the numbers! Reducing the values makes the calculation easier to visualize and reduces the chance of errors. For example, start by focusing on even numbers.

Method 2 - Multiply Before Dividing 🔦
Leverage the power of Base 10! By scaling up numbers to align with familiar "10 Facts," you can streamline the entire process. For instance, work with multiples like 5 or 25 for smoother calculations.

Method 3 - Split the Divisor 🫲
Break the divisor into smaller parts to simplify the equation. Dividing step-by-step with smaller chunks speeds up your thought process and keeps calculations manageable.

🎀 Pro Tip: Breaking numbers isn’t just for division—it’s equally effective for addition and multiplication!

Example:
18 x 7

Break 18 into 2 x 9.
Rearrange the equation: 7 x 9 x 2.
First, solve 7 x 9 = 63.
Then multiply 63 x 2 = 126.
Master these strategies, and calculations will feel effortless!
