Today in class, we learned about subtracting integers. In the beginning of class, Mr. H. talked about asking questions and not being shy. Then, he took a nap and gave us two integer questions to do with a partner, then some people went up to the smart board to solve the questions. Those questions were:
(+2) - (+6) + (-2) = ?
(+2) + (-6) + (-2) = -6
(-2) - (+5) + (-4) = ?
(-2) + (-5) + (-4) = -11
When we finished solving those questions, he gave us homework to do. Our homework is pages 48 and 49. For page 48, we have to do questions 21, 22, 23, 27, 29, 30, 37, 38, 39, 40. For page 49 we have to do questions 9, 10, 11, 14, 15, 25, 26. Here are two questions from page 48.
21. (-10) + (-8) - (-6) - (+2) =
(-10) + (-8) + (+6) + (-2) = -14
23. (+2) - (+6) + (-5) - (-9) =
(+2) + (-6) + (-5) + (+9)= 0
If there was a subtraction part, you have to change it to an addition statement then add the opposite.
(+2) - (+6) + (-2) = ?
(+2) + (-6) + (-2) = -6
(-2) - (+5) + (-4) = ?
