Doing mathematical calculations in “the head” or mental calculations require significant amounts of working memory. Children need to store the information they have heard, be able to remember and retrieve those facts, and then process the information and apply it correctly. Because “doing math” is not a unitary skill. It involves a long list of cognitive abilities, in each of which children vary widely in terms of abilities.
Our ability to perform arithmetic operations depends largely on working memory, manipulating and keeping information in mind. Previous research has found that, in adults, procedural strategies, in particular counting, rely on working memory to a greater extent than recovery strategies. During childhood, there are changes in the types of strategies employed, as well as an increase in the precision and efficiency of the execution of the strategies. As such, it seems likely that the role of working memory in arithmetic may also change, however, it has never been directly compared to children and adults.
This study used the traditional dual-task methodology, with the addition of a load control condition, to investigate the extent to which the working memory requirements for different arithmetic strategies change with age, between 9 and 11 years old, between 12 and 14 years old, and early adulthood. We show that both children and adults use working memory to solve arithmetic problems, regardless of the strategy they choose. This study highlights the importance of considering working memory to understand the difficulties that some children and adults have with mathematics, as well as the need to include working memory in theoretical models of mathematical cognition. Difficulties within a single cognitive domain that is required for mathematics will make it difficult for children to perform mathematical calculations.

Many of the numbers can be “fractionated” once students are more familiar with and master fractions, and they can also use mathematical data retrieval for many items instead of having to calculate every single one of them. There is an enormous correlation between doing mathematics in your head using the visual algorithm and considering that “you are not very good at mathematics”.
And I found a person, if I remember correctly, who does mathematics visually and considers himself very good at it. . Not having the cognitive skills necessary to fully understand mathematical concepts can cause information to be lacking or inaccurate and cause frustration, as well as an aversion to mathematics or mathematical anxiety. If a student is distracted while doing a mathematical calculation, this easily overloads their working memory and disrupts their thinking.
Latest news and articles on neuroscience, pedagogy and research-proven approaches to mathematics learning for elementary, middle and high school students. I would like to hear from someone who has done mental calculations at a proficient level about what methods they use and if they do so visually. I have met mathematics students who excel at some types of mathematics, but are terrible at numerical calculations and do mathematics using the visual algorithm. This animated article and blog explores the cognitive science of learning mathematics, explaining how different types of memory are involved, why speed is important and how practice is key to developing fluency in mathematics.
For example, I think that knowing aphantasia is important to understand why some people are good at mental mathematics. .
