Order these numbers from least to greatest. −10.7 , −113 , 10710 , −12011

When dealing with negative numbers, the higher the number, the less it is. So, the lowest number is -12,011. Then, it would be -113, -10.7, and finally 10,710 because it is the only positive number. The final order is:

-12,011, -113, -10.7, 10,710

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
