Celebrating Maths 2.0 Day - 8th July 2022

Math 2.0 Day is celebrated every year on the 8th July.  It's a holiday that commemorates the importance of the combination of math and technology.

The day was formed to celebrate the accomplishments made through the combination of the field of math and technology, and how it can benefit the world in the coming years. This means without math, it would have been impossible for us to be provided with the different travel and entertainment mediums we have today. Nor would we have the technology we use to accomplish several everyday work tasks. So if you love how easy technological innovations have made your life, celebrating Math 2.0 Day is a must!

Take a look at this maths problem.

The Answers

Computer = 30                Mobile = 20                 Keyboard= 6

Scissors = 9                     Highlighter = 1             Stapler = 29

 The Workings

 If we call the computer x, the mobile y and the keyboard z,

 we know that:                  3x + y = 110

and                                      2x + 2y = 100

These are simultaneous equations.

If 3 x + y = 110, then y = (110 – 3x).

You can substitute (100-3x for y in the second equation to find x

2x + 2(110 – 3x) = 100

2x + 220 – 6x = 100

-4x = 100 – 220

-4x = -120

X = 30

Now substitute 30 for x in one of the equations to find the value of y:

Then you can work out the value of z !!
