Question

1. Write properties of integers of addition, subtraction, multiplication and division on a chart paper Decorate the border using colors. 2. Represent the given situation diagrammatically and mathematically. Situation- A frog is there in a 12m deep well. The frog wants to jump out of the well. Every time he jumps 3m and falls back by Im. (1) Use different colors for positive and negative integers (11) In how many jumps will he come out of the well? (111) Which value do you learn from the frog? 3. Play with balls Description: Students are supposed to take two different colored sketch pens, same number of identical balls are to be drawn for one integer as indicated. Perform activity according to given example. (We know-Ve symbol means opposite /change of color) Example: Let, Green for +Ve integer Red for -Ve integer EXAMPLE 1) 2 x 3 (2 times 3) 1) 2x 3 (2 times 3) (+3) (+3) (+6) 2) - 2 x-3 * -2X(-3) =+ 2 times (20) 263 [..+..]=-::: The colour Show the following in the form of pictures of balls. (i) - 3x4 (ii) 2x -4. (11) -4 x-3 (iv) 4 x 5​

Answer 1

Answer:

All properties and identities for addition, subtraction, multiplication and division of numbers are also applicable to all the

Answer 2

All of the properties and identities that apply to numbers in addition, subtraction, multiplication, and division also apply to integers.

The following are the five main properties of operation for integers:

• Closure Property
• Associative Property
• Commutative Property
• Distributive Property
• Identity Property

1. Solution:

Height = 2×= 10m

He needs 6 jumps to come out of the well.

    2. Solution

3 balls + 3 balls=6 balls
