34?
You get 50.
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.

Whether the change is an increase or decrease . . . -- Divide the new number by the original number. -- Multiply the result by 100. -- Subtract 100. -- Now you have the percent of change.
To estimate, you round the number to the nearest 10 and add, subtract, divide, or multiply. If the number is a decimal (ex. 12.132), you would round it to 12, and then round that to 10.
If you add, subtract or multiply rational numbers, the result will be a rational number. It will also be so if you divide by a non-zero rational number. But division by zero is not defined.
Divide the new number by the original number, subtract '1', and multiply by 100.
You get 50.
You have to make make 24 with the 3 numbers they gave you. Once you Add, Subtract, Multiply, or Divide, you click the answer of the problem's answer and you Add, Subtract, Multiply, and Divide by the number you have left.
No, a negative number cannot be simplified because it is a whole number. Therefore, you can only multiply, divide, subtract, and add it.

It stands for Divide, Multiply, Subtract, and bring Down. This is used in long division. You divide the number on the left into the one on the right, placing your answer on top of the bracket. Then, you multiply the number on top of the bracket with the number on the left, placing this answer below the right-hand number. You subtract the number on the very bottom from the right-hand number. Then, you bring down the next numeral available underneath the bracket.

Yes. To do the calculation by hand you can subtract 32 from the original number, multiply that by 5, and then divide by 9.
You can add, subtract, multiply, or divide both sides of the equation or inequality by the same number. Don't multiply or divide by zero. In the case of an inequality, if you multiply or divide by a negative number, the sign of the inequality must be reversed. E.g., if you multiply both sides by -2, a "less-than" sign should be replaced by a "greater-than" sign.
