Ineed with finding out the blank spaces

2 times what plus 1 equals five? we know it must be a small number, so we go with 2. in this case:
2(2)+1 does equal five.
the triangle= 2
so we have next,
2 + a square which equals 1.
we subtract the 2 from both sides
and find out that the square = -1
next, we have
2-2(-1)
the negatives cancel out since it is multiplication and we get:
2+2
the star =4
hope this helped!! xx

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)
