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: Same as above
Perform the calculation: 432 ÷ 24 = 432 × (1/24) = 432 × (5/120) = 18
Visualize the numbers: Imagine subtracting 24 repeatedly from 432.
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.
Verify your answer: Check that the answer is reasonable and accurate.
Here are two sample problems and solutions using the Think Mental Math method:
Estimate the answer: 40 × 20 = 800 (so the answer should be around 700-800)
