Max/Min error Mathematics problem

Question

Given an equation R = PQ, whereby P and Q has a max error of 2% and 5% respectively, what is the maximum positive and maximum negative error of R?

Max:

R = 1.02P * 1.05Q = 1.071PQ
Max % = (1.071 - 1) * 100 = 7.1%

Min:

R = 0.98P * 0.95Q = 0.931PQ
Min % = (0.931 - 1) * 100 = -6.9%

An article on Technet help solve my trouble. To stop FortiClient from starting automatically, try the following:

The system could have been better if we alighted not on the runway and at a place with shelter.

We then took a bus from the airport straight to our camp, Hengchun Camp. The journey was long. It was too early a morning and so all the shops along the way were not opened. I could see mountains everywhere.

Hengchun Camp was more like an old camp to me. The camp was there for more than 30 years. The external looked average but then the internal revealed itself. More than 50 soldiers were made to live in a bunk! Fans were not enough! Toilets were at another block and so we actually had to cross to another block just to use the toilet. Toilet facilities were bad too. Some of the showers let out water that could boil an egg! Those were condemmed. The first d…
