Answer:
212
Step-by-step explanation:
<u>Rule</u>
- Subtract the 2nd number from the first to obtain the first digit(s) of the answer.
- Add the 2nd number to the 1st to obtain the last digit(s) of the answer.
5 - 3 = 2
5 + 3 = 8
Therefore: 28
9 - 1 = 8
9 + 1 = 10
Therefore: 810
8 - 7 = 1
8 + 7 = 15
Therefore: 115
6 - 2 = 4
6 + 2 = 8
Therefore: 48
7 - 5 = 2
7 + 5 = 12
Therefore: 212
Answer:
212
Step-by-step explanation:
Simple addition and subtraction is to be used here.
<u>5, 3 = 28 </u>
5-3 = 2 , 5+3 = 8
<u>9 , 1 = 810</u>
9-1 = 8 , 9+1 = 10
<u>8 , 7 = 115</u>
8-7= 1 , 8+7 = 15
<u>6</u><u> </u><u>,</u><u> </u><u>2</u><u> </u><u> </u><u>=</u><u> </u><u>4</u><u>8</u>
6-2 = 4 , 6+2 = 8
<u>7</u><u> </u><u>,</u><u> </u><u>5</u><u> </u><u>=</u><u> </u><u>2</u><u>1</u><u>2</u>
7-5 = 2 , 7+5 = 12
