Question

Insert parenthesis to make each equality true.
1+2*3+4*5=65

Answer 1

Answer:To make the equality 1+23+45=65 true by inserting parentheses, you can group the numbers and operations in the following way:

(1+2)*(3+4)*5 = 65

This can be calculated as:

3 * 7 * 5 = 65

So, by adding parentheses as (1+2)(3+4)5, the equality 1+23+45=65 becomes true.
