Question

(Question- 8)Verify a-(-b)=a+b for the following values of a and b.
(i) a = 118, b= 125
(ii) a=28, b= 11
(iii)a=21, b = 18
(iv) a = 75,b=84​

Answer 1

(i)

a)

$\mathcal\pink{a - ( - b) = a + b}$

$\mathcal\green{if \: \: a = 118 \: \: and \: \: b = 125}$

$\mathcal\blue{118 - ( - 125) = 118 + 125}$

$\mathcal\red{118 + 125 = 243}$

$\mathcal\orange{243 = 243}$

$\mathcal\pink{l.h.s. = r.h.s.}$

$\mathfrak\green{hence \: verified}$

(ii)

$\mathcal\pink{a - ( - b) = a + b}$

$\mathcal\green{if \: \: a = 28 \: \: and \: \: b = 11}$

$\mathcal\blue{28 - ( - 11) = 28 + 11}$

$\mathcal\red{28 + 11 = 39}$

$\mathcal\orange{39 = 39}$

$\mathcal\pink{l.h.s. = r.h.s.}$

$\mathfrak\green{hence \: verified}$

(iii)

$\mathcal\pink{a - ( - b) = a + b}$

$\mathcal\green{if \: \: a = 21 \: \: and \: \: b = 18}$

$\mathcal\blue{21 - ( - 18) = 21 + 18}$

$\mathcal\red{21 + 18 = 39}$

$\mathcal\orange{39 = 39}$

$\mathcal\pink{l.h.s. = r.h.s.}$

$\mathfrak\green{hence \: verified}$

(iv)

$\pink{a - ( - b) = a + b}$

$\green{if \: \: a = 75 \: \: and \: \: b = 84}$

$\blue{75 - ( - 84) = 75 + 84}$

$\red{75 + 84 = 159}$

$\orange{159 = 159}$

$\pink{l.h.s. = r.h.s.}$

$\mathfrak\green{hence \: verified}$
