Bilingual people process maths differently depending on the language
As if maths wasn't confusing enough...

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.
At such a critical moment in US history, we need reporters on the ground. Your donation allows us to keep sending journalists to speak to both sides of the story.
The Independent is trusted by Americans across the entire political spectrum. And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.

Intuition enables the brain to recognise numbers up to four. However, when calculating mathematical problems, we depend on language.
This fact led researchers at the University of Luxembourg to explore just how the arithmetic skills are affected when bilingual people use different languages.
The study’s authors recruited students for whom Luxembourgish was their mother tongue and had carried on studying in Belgium and were therefore fluent in both German and French.
In two distinct tasks, participants were asked to solve a mixture of simple and complex maths problems in both languages.
While they were able to solve the simple tasks with equal proficiency, they took longer to calculate the complex task in French and made more errors than they did when doing the identical task in German.
Their brain activity was measured by functional magnetic resonance imaging and the results showed that different regions of the brain were in use when the participants were solving problems in different languages.
For example, when solving the simple task in German, a small section of the left temporal lobe was activated.
However, with the complex French tasks, the part of the brain that processes visual information was active.
Thus, researchers concluded that “extra effort” was needed to solve mathematical problems when doing so in their non-native tongue.
“The research results clearly show that calculatory processes are directly affected by language,” the author’s wrote.
They noted that this evidence will gain importance in due course thanks to increased migration and an expanding globalised job market.
