2 x 3 x 5
= 6 x 5
= 30
3± × 26
= This cannot be.
But That sign after three is called "plus - minus"
If we will remove the multiplication sign, this will be the solution with answer.
3± × 26
= 3 + 26
= 29
= 3 = 26
= -23
= 29 AND -23
If we will remove the "plus-minus" sign, the solution will be...
3 x 26
= 78
34 x 66
= 2244
