Question

Find the value of
(i) |−9|
(ii) |−36|
(iii) |0|
(iv) |15|
(v) −|−3|
(vi) 7 + |−3|
(vii) |7−4|
(viii) 8 −|−7|

Open in App

Solution

i) The value of |-9| is 9
ii) The value of |-36| is 36
iii) The value of |0| is 0
iv) The value of |15| is 15
v) The value of |-3| is 3
$∴$ -|-3| = -3
vi) 7 + |-3|
= 7 + 3 (The value of |-3| is 3)
= 10
vii) |7 - 4|
= |3|
= 3 (The value of |3| is 3)

viii) 8 - |-7|
= 8 - 7 (The value of |-7| is 7)
= 1
