academic math concepts - addition and subtraction In mathematics, especially for early learners, the concepts of "before" and "after" refer to the position and sequence of numbers within the counting system. They are foundational to developing number sense and understanding basic arithmetic.
"Before" number: The number that comes immediately preceding a given number in a sequence (moving backward on a number line, or subtracting one). For example, the number before 8 is 7.
"After" number: The number that comes immediately following a given number in a sequence (moving forward on a number line, or adding one). For example, the number after 8 is 9.
