Maths is useful in many different ways. For example: Engineering, Technology, Science etc.
It can be used in Engineering for measurements, dynamics, etc. It can also be used in Technology for boolean inputs, binary, hexadecimals, etc. Furthermore, It can be used in Science for calculations, ratios, measurements etc. Have a look at these games : http://www.bbc.co.uk/bitesize/ks2/maths/
Many scientists, engineers, technologists find maths useful. Consequently, they have made many creations, like robots, potions, discoveries etc. Have a look at these pictures:
This is ASIMO. ASIMO is a robot that can do many things, like serving food, play sports etc. Honda was responsible for building this amazing robot
Maths is used to create the robot- binary, hexadecimals,dynamics,measurements,etc
It also used to create Ammonia- the number of atoms required to create the molecule, the number of atoms to create many of the same molecules etc. Furthermore, it used in the 3D Printer- binary, measurements etc.
This is AMMONIA. Ammonia is created by one Nitrogen atom and three hydrogen atoms.
