====// A.) //// Describe any patterns you observe in the way the differences change as the integers subtracted from 15 get smaller. //====

==== - The end sum gets larger by one each time ==== ==== - The integers being subtracted from 15 get smaller by one each time ==== ==== - The number 15 stays consistent ====

====// B.) //// Use the patterns that you observe to predict the answer to 15 - ˉ1. Check you prediction using a chip board or number line. //====

====// C.) //// Predict the answer to 15 - ˉ4. Explain your reasoning //====

====// 1.) //// Study the equations bellow. //====

====// A.) //// Describe any patterns that you observe in the way the differences change as the integers subtracted from ˉ10 get smaller. //====

==== - The difference gets smaller by one each time ==== ==== - The integer being subtracted from //ˉ//10 gets larger by one each time ==== ==== - // ˉ // 10 always stays the same ====

====// B.) //// Use the patterns that you have observed to answer ˉ10 - ˉ1. Check your answer by using a chip board or a number line. //====

====// C.) //// Predict the answer for ˉ10 -ˉ6. Explain your reasoning. //====

====// 2.) //// When you add two negative integers, you get a negative sum. When you subtract two negative integers, do you always get a negative difference? Explain. //====
