Answer: n = 3; n represents a remainder in a division problem.


Step-by-step explanation:


1) Finding n:


i) Given: 643 = 4 × 160 + n

ii) Do the operations: 643 = 640 + n

iii) Subraction property of the equality: 643 - 640 = n

iv) Do the operations: 3 = n

Answer: n 3


2) Meaning of n


When you divide 643 by 4 the quotient is 160 and the remainder is 3, because 160 × 4 = 640, and 643 - 640 = 3.


This is, 3 is what is left when you split 643 into 4 getting 160 whole parts (plus the remainder, 3).
