FAQs on Textbook: Whole numbers (Term 3) - Mathematics for Grade 6

1. What are whole numbers?
Ans. Whole numbers are all the non-negative integers, including zero. They are the numbers you use to count objects, such as 0, 1, 2, 3, and so on. Whole numbers do not include fractions or decimals.
2. How do you add whole numbers?
Ans. To add whole numbers, you simply combine their values together. Start from the rightmost digits and move left, carrying over any value if the sum exceeds 9. For example, to add 23 and 45, you would do 3 + 5 = 8, and 2 + 4 = 6, giving you a total of 68.
3. Can whole numbers be negative?
Ans. No, whole numbers cannot be negative. They only include zero and positive integers. If a number is negative, it is classified as an integer but not a whole number.
4. What is the difference between whole numbers and integers?
Ans. The main difference is that whole numbers include all non-negative numbers (0, 1, 2, 3, ...) while integers include all positive numbers, negative numbers, and zero (..., -3, -2, -1, 0, 1, 2, 3, ...). So, all whole numbers are integers, but not all integers are whole numbers.
5. How do you multiply whole numbers?
Ans. To multiply whole numbers, you take one number and add it to itself repeatedly based on the value of the other number. For example, to multiply 4 by 3, you would add 4 three times: 4 + 4 + 4, which equals 12. Alternatively, you can use the multiplication table for quick reference.
