Question

add7 sets of 8to 144
​

Answer 1

Step-by-step explanation:

We are given a list L=[a1,...,an] where ai∈R . We wish to find all ways that a number k can be made from these numbers, by applying any of a set S of binary operations to consecutive pairs of them, reducing the list by 1 element each time. Note that we are not allowed to rearrange the list.

For our specific question, we have L=[7,8,9,−7,−8,−9] , k=144 , and S={+,−,∗,/} (representing addition, subraction, multiplication, and division, respectively).
