Call the unknown number n. Then, from the problem statement, {4[(n + 7 - 2) - n]} - 2 = 18. This is always true because [(n + 7 - 2) - n] is simply 5.
Multiply two odd numbers Add an even and an odd Subtract an odd and an even
You can always do that.
-5+-3 = -8 ++ Add -- Add +- Subtract -+ Subtract
just change the fration with the smallest denominator and add or subtract the way you always do.
Yes.Yes.Yes.Yes.
the result is always even

Pick any number. Multiply by 6. Add 13. Subtract 7. Divide 3. Divide 2. Then subtract by the original number you chose. Your result will always be 1. Tell a friend to mentaly multiply their age by 2. Tell them to add 14 then divide 2. Ask your friend what number they currently have. Now, you mentally subtract 7 from the number they tell you, then you'll know your friend's age.
No.If you subtract a positive number, you move to the left.If you subtract a negative number, you move to the right.
Prices posted after a race are based on a $2 bet. So, subtract 2 from the posted amount, multiply the remainder by 2.5 (because 5 divided by 2 is 2.5), and then add in your $5 bet. For example, if a horse paid $8.00 to win, subtract the original $2 bet to get $6.00. (Your original bet is always included in the payout). Multiply $6 times 2.5 to get $15. Add in your $5 bet and you will collect $20 when you cash your ticket.
1. Pick a number 2. Multiply by two 3. Add 12 4. Subtract 8 5. Halve it (Divide by 2) 6. Subtract original number ... HOPE THIS HELPSSS <3333
