Aliyah had some candy to give to her four children. she first took ten pieces for herself and then evenly divided the rest among her children. each child received two pieces. with how many pieces did she start?

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)
