Solution:Even numbers are divisible by 2. Counting numbers less than 10: 1, 2, 3, 4, 5, 6, 7, 8, 9 So, even numbers less than 10: 2, 4, 6, 8 Example 4. In the figure below, observe the pattern and find the number of dots in the fourth box. ...
In mathematics, for a number, x, to be divisible by a number, k, it must be the case that x = kp, where p is an integer. We can use this property of divisibility to prove various propositions and solve various problems within the study of mathematics....
