Question

2
(ii) negative integers whose difference is - 3.
(in) a negative and a positive integer whose difference is -5.
(iv) a positive and a negative integer whose difference is more than 10.
4. The difference of two integers is - 10. If one of them is 16, find the other integer.
difference in outside and inside temperature of the cold storage?
MULTIPLICATION OF INTEGERS
Multiplication is repeated addition of integers.
1. Multiplication of two positive integers : When both integers are positive, then we multiply
values regardless of their signs and assign the positive (+) sign to the product.
For example: 8x9=72,
11x12=132
2. Multiplication of two negative integers : When both integers are negative, then we
multiply
5. On a certain day, the temperature outside a cold storage was 35°C and inside it was -10°C. What was the difference in outside and inside temperature of the cold storage​

Answer 1

i) (-6)-(-3)

ii)10-(-5)

iii)Let other integer =x

x-16=(-10)

x= -10+16

x=6

multiplication of integers

2 (-3)×(-2)

=6

5.difference =35-(-10)

=35+10

=45°C
