Question

1.The successor of the smallest whole number is:
2.The addictive identify for whole number is:
3.20+(25+7)=(20+25)+7 is an example of which property of addition?
4.If two whole numbers are multiplied the product is always a_____
5.if a x a=a,then number of possible values of a are:
6.Which of the following numbers represents a triangle in dot pattern?
7.Which smallest number can be represented both as a square and a triangle in dot pattern?​​

Answer 1

1. The smallest whole number is 0 and thus the successor of 0 would be 1.

2. 0 is the additive identity for whole number.

3. 20 + (25 + 7) = (20 + 25) + 7 is an example for associative property.

4. If two whole numbers are multiplied the product is always a whole number.

5. If a × a = a, then number of possible values of a are either 1 or 0. This is because 0 × 0 = 0 and 1 × 1 = 1 and as we can see that a × a = a here.

6.  Some numbers like 3, 6 and 10 can be arranged as a triangle in a dot pattern.

7. The smallest number that can be represented as a square and a triangle in a dot pattern is 36.
