When you are using calculators, finish the obvious steps by yourself before you enter numbers in your calculators. The less you enter in a calculator in each step, the more likely you will avoid mistakes. For example, suppose you need to calculate (200+50)* (1+6.1/100)^(25+3). Enter 250"(1.06128) instead of the original expression. Mind the parenthesis around 1.061^28. Please use your calculator to find the value of the following expression: (234+3)*(1+8/100)^(6+6)
