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

Answer:

1. 1

2. its negative

3. associative property

4. whole number

5. 1

Answer 2

Answer:

1. The smallest whole number is 0

Hence the successor of the smallest whole number 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 a is either 1 or 0.

Hence if a x a=a,then number of possible values of a are

6.  Some numbers like 10 , 15 and 21 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.
