Numeracy is the ability to understand, interpret, and use numbers effectively in everyday life. It goes beyond basic arithmetic, encompassing [[logical reasoning]], [[Problem solving|problem-solving]], and the ability to apply [[math]]ematical concepts to real-world situations. Whether managing personal finances, interpreting data, or making informed decisions, numeracy is a fundamental skill for modern living.
