Answer:

8+8-1 = 15

Step-by-step explanation:

The doubles minus one is the technique to add two numbers which are consecutive.In this technique you add double the greatest number of the two consecutive and then subtract 1 from the result.

Here we have equation 8+7.

so doubling the greater number (8+8) or (8*2)  gives us 16.

then subtracting 1 from it (16-1) gives us 15

so 15 is our answer.

Using the doubles minus one strategy, the greater value of the expression is doubled and one subtracted from the sum. Hence, we have 8 + 8 - 1 = 15

Given the expression :

8 + 7

The greater value of the two digits is 8

Doubling the greater value : 8 + 8

Subtracting 1 from the sum of the doubled digit :

8 + 8 - 1 = 8 - 7 = 15

Therefore, the result of the expression is 15
