1 plus 2 plus 3 x 5 x 7 plus 89

9,348

Explanation:

In order to carry out this calculation, the mathematical separation rules must be taken into account. Thus, 1 + 2 + 3 x 5 x 7 x 89 should be solved as follows:

1 + 2 + (3 x 5 x 7 x 89)

3 + 9,345

9,348

This is so because the multiplications must be solved together, while the addition and subtraction must be separated from each other for the correct resolution of the given calculation. If this calculation is solved without separating, the result would be incorrect.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
