Products and Sums
The below QuickQuestion Interface © generates 10 random questions to do.
Each question tells you the sum and the product of a pair of numbers, and you have to calculate what the original numbers are.
Choose what maximum value for the numbers you would like, and if you would like to include negatives as well.

Ideas for Teachers
This is a good alternative to the QQI activity, if you just want to put 10 questions on the board. Then you can get answers from students to enter in the boxes before checking them, and correcting as necessary.
However, the real power in this activity is when you get the students using it themselves. In a computer lesson, set them all going on the activity, and get them to repeat until they get every question correct.
Or you can set it as a homework, telling them the conditions to use (different conditions for different students to differentiate the homework). Then get them to do one or two sets, all correct, and to take a screen shot and either email it to you, or, even better, stick it in their books. Since the questions are random, every student will get a different set of questions, and the immediate feedback means they can go back and correct their work straight away.
Getting them to do one of the random settings will make them pay attention and show a true understanding.
For the more able, getting them to do a strange accuracy, such as to the nearest 7 or 15, will have them practising times tables too.
