Kids between the ages of 4 and 6 may have an innate ability to solve algebra problems long before they have had a single math class, according to new research from Johns Hopkins University.
"These very young children, some of whom are just learning to count, and few of whom have even gone to school yet, are doing basic algebra and with little effort," post-doctoral fellow Melissa Kibbe, the study's author, said in a statement. "They do it by using what we call their 'Approximate Number System:' their gut-level, inborn sense of quantity and number."
The "Approximate Number System," or ANS, is also called "number sense," and describes humans' and animals' ability to quickly size up the quantity of objects in their everyday environments. Humans and a host of other animals are born with this ability and it's probably an evolutionary adaptation to help human and animal ancestors survive in the wild, scientists say.
Previous research has revealed some interesting facts about number sense, including that adolescents with better math abilities also had superior number sense when they were preschoolers, and that number sense peaks at age 35.
