Answer 1

Answer:

3. M

fr

(6 and 3 are less than-1. T ( 8- (-8) - 16 7

(W) ( 90) + 5 = -16 F

(iv) (-7) (-3) * (-5) * 2 = -120 F

(1) What is the difference between - 7 and -10?

(-10

- 3.

(W) Give an example to show that the subtraction of two integers is not commutative.

(i) Verify (-11) * (-5) + (-7)} - {(-11) * (-5)} + {(-11) * (-7)}

(iv) Evaluate (-40) + 5) + 2

(v) Write down the pair of integers whose sum is 0.

(1) What is (-8) * I equal to?

(ii) Which property is used here, (-5) + [18+ (-8)] = [-5 + 18] + (-8)?

(it) What is -- 75 + O equal to? Also state the property.

(iv) Write the following integers in ascending order : 6,0-2, 1, 5, 4

(1) Write a negative integer and a positive integer whose difference is -4.

(ii) Use distributive property of multiplication over addition, find the value of 12 * 15.

(ii) Write two integers which is smaller than - 7 but their difference is -7.

(iv) An elevator descends into a mine shaft at the rate of 8 m/min. If the descent starts from 20 m above ground

level, how long will it take to reach 460 m.
