Think Mental Math is an approach to mental calculation that involves using visual imagery and a systematic method to solve mathematical problems. It was developed by Arthur Benjamin, a mathematician and mental math expert, who advocates for the use of mental math techniques to improve mathematical ability and build confidence.

Here are two sample problems and solutions using the Think Mental Math method:

18

Perform the calculation: 432 ÷ 24 = 432 × (1/24) = 432 × (5/120) = 18

In today's fast-paced world, being able to perform mental calculations quickly and accurately is a valuable skill. Mental math can help you make informed decisions, solve problems efficiently, and even improve your cognitive abilities. In this write-up, we'll explore the concept of Think Mental Math and provide two answers to help you get started.

Estimate the answer: 40 × 20 = 800 (so the answer should be around 700-800)

Perform the calculation: 432 - 24 = 408, 408 - 24 = 384, ... 384 - 24 = 360, ... 18 times.

Calculate 432 ÷ 24
