👉 In mathematics, "renumbers" refers to a process of renaming or changing the numbers in an expression. This can be done by multiplying each number by a specific factor or by performing arithmetic operations on them. For example, consider the expression 3x + 2y - z. If we renumber these terms as follows: - x = 3 - y = 1 - z = 2 Then, the new expressions would be: - 3x = 3
