The lack of ability to understand or work with numbers and mathematical concepts.
Many people struggle with innumeracy, making it difficult for them to manage their finances effectively.
Innumeracy is formed from "in-" (meaning not) and "numerus" (meaning number) combined with the suffix "-acy" (indicating a state or quality). The word describes the state of being unable to understand or work with numbers.
Think of 'not' ('in-') being able to understand 'numbers' ('numerus') — that's why innumeracy means the inability to deal with numbers.
