Question

17.2+13.4-(21.2×2.2)+1.2÷0.06

Answer 1

for this type of expression we use BODMAS (bracket of division multiplication additional and subtraction) rule

so first solve bracket

17.2+13.4-(21.2×2.2)+1.2÷0.06
= 17.2+13.4-46.64+1.2÷0.06

now divide

=17.2+13.4-46.64+1.2÷0.06
=17.2+13.4-46.64+20

now multiple ( nothing is left to multiple)
now add

=17.2+13.4-46.64+20
=30.6-66.64

now subtract

=30.6-66.64
= -36.04
