SU🧠A squary tip for squaring numbers near 100 ⚡️
e.g. 96²
✨How far is it from 100? It’s 4 LESS
✨We do 96-4. This gives us the first part of our answer: 92
✨We do 4². This gives us the second part of our answer: 16
96²=9216 🤯
e.g. 105²
✨How far is it from 100? It’s 5 MORE
✨We do 105+5. This gives us the first part of our answer: 110
✨We do 5². This gives us the second part of our answer: 25
105²=11025 🤓
⛔️ We always need a 2 digit answer from the second part, so if we get a 1 digit answer in the last step, add a 0 in front of it.
