Addition and Subtraction

It never hurts to go back to our grade school beginnings on occasion to refresh the principles of basic

arithmetic. Consider solving the following equations calisthenics for the brain — Try doing some by

Note – Some of these equations have an incorrect answer…can you find them?

8+3.2=11.2 7.5+22.66=30.06 6.3-4.1=2.2 43.2+99.1= 142.3 1001.892-238.451=763.351

25,674.09+14.477=25,688.57 -2.34-56.098=-58.438 0.071+0.193=0.264 1,000,000-2.31=999,998.69
