If c3535 - 355bc = abc1 find number abc. Multiple solutions may exist.
The aim is to place the some numbers from the list (19, 21, 22, 24, 28, 30, 65, 68, 74, 89) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A*B-C.
Look at the series (17, 51, 204, 1020, 6120, ?), determine the pattern, and find the value of the next number!

Sandblasting

In 1870, sandblasting was patented by Benjamin Chew Tilghman (26 Oct 1821 - 1901). Compressed air forces sand as an abrasive material through the nozzle of a sandblasting gun. A popular myth holds that Tilghman, when a General in the army, had seen the effect of wind blown sand upon glass windows, in the desert. The sand has etched the glass where unprotected and revealed the contrast against parts that were covered by steel mesh. He has been called the "father of shotpeening." In 1866, he found sulphurous acid would dissolve the intercellular matter of wood, freeing the fibres for pulp, and became famous as the inventor of the sulphite process to make wood pulp for paper production.

The birds and the tee's?

A father spoke to his son, "It's time we had a little talk, my son. Soon, you will have urges and feelings you've never had before. Your heart will pound & your hands will sweat. You'll be preoccupied and won't be able to think of anything else."

He added, "But don't worry, it's perfectly normal... it's called golf."
