I have no perfect answer.

mathematics plays a key role in daily life its simple 
applications in daily life are as follows;
1.it is used in simple calculations like in stores,shops 
and in offices etc.
2.As mathematics is the language of science so it provide 
us a better understanding to understand science like 
physics and chemistry.
3.If we want to construct a building we have to survey its 
all area and without mathematics the measurements is not 
possible.
4.if we want to know how many population is in our country 
we keep census it is also a best application of Mathematics
5.As computer science is used in every field of life 
mathematics play a key role in this field as it based on 
binary number system (0,1) and every work of computer is 
done in boolean algebra and it is also an application of 
maths.

Except this there are millions of daily life examples of 
maths, but i think these are enough.
