Ok here's a cool math trick that will give you an answer with your age and the number of siblings you have

1. Take Your age

2. Multiply your it by 2

3. Add 10 to the number you got in step 2

4. Multiply that number by 5

5. Add # of siblings you have

6. Subtract 50

i am so confused... i got -15... what does it mean????? how is this cool???? How will this help me with math???????????????????
