Math
Place value
The idea that a digit's position sets its value (the 2 in 25 means 2 tens).
Place value is understanding that where a digit sits determines what it is worth: in 347, the 3 means three hundreds, the 4 means four tens, and the 7 means seven ones. It is what makes multi-digit addition, subtraction, and 'carrying' make sense.
