(b) difference is –10
(c) sum is 0
NCERT Class 7th Mathematics Chapter 1 Integers

Answer 1

Answer:

${\bf\underline\green{Given~:-}}$

a) Sum is - 7 -

$\large\pink\implies$ (9) + (-2)

${\bf\underline\green{To find :-}}$

$\large\blue\implies$ -9 - (-2)

$\large\red\implies$ -9 + 2

$\large\orange\implies$ -7

b) Difference is -10-

$\large\pink\implies$ (-4) - (+6)

${\bf\underline\green{Solution~:-}}$

$\large\blue\implies$ (-4) - (+6)

$\large\red\implies$ -4 - 6

$\large\orange\implies$ -10

c) Sum is 0-

$\large\pink\implies$ (10) + (-10)

${\bf\underline\green{Solved~:}}$

$\large\blue\implies$ 10 - (-10)

$\large\red\implies$ 10 - 10

$\large\orange\implies$ -0

Hence Proved !!

Your answer is 0 $\large{\bf\green{✓}}$

Answer 2

Answer:

Answer:

{\bf\underline\green{Given~:-}}

Given :−

a) Sum is - 7 -

\large\pink\implies⟹ (9) + (-2)

{\bf\underline\green{To find :-}}

Tofind:−

\large\blue\implies⟹ -9 - (-2)

\large\red\implies⟹ -9 + 2

\large\orange\implies⟹ -7

b) Difference is -10-

\large\pink\implies⟹ (-4) - (+6)

{\bf\underline\green{Solution~:-}}

Solution :−

\large\blue\implies⟹ (-4) - (+6)

\large\red\implies⟹ -4 - 6

\large\orange\implies⟹ -10

c) Sum is 0-

\large\pink\implies⟹ (10) + (-10)

{\bf\underline\green{Solved~:}}

Solved :

\large\blue\implies⟹ 10 - (-10)

\large\red\implies⟹ 10 - 10

\large\orange\implies⟹ -0

Hence Proved !!
