+7 + 1 - 3 + 4 -2 - 5 + 7 - 2 + 1 -6 + 5(ii)+2 - 3 + 2 -5 + 1 - 3 + 8 - 4 + 3

Academic Mathematics NCERT Class 7

Solution:

i) $+7 + 1 - 3 + 4 -2 - 5 + 7 - 2 + 1 -6 + 5$

Using BODMAS rule

=$7 + 1 + 7 + 4 + 1 + 5 - 3 -2 -5 -2 -6$

= $25 - 18 $

=7

ii)$+2 - 3 + 2 -5 + 1 - 3 + 8 - 4 + 3$

Using BODMAS rule

= $+ 2 + 2 + 1 + 8 + 3 - 3 - 5 - 3 - 4$

= $16 - 15$

= 1
