How can you express the number 100 using six 9s. You have to use them all of them You can add subtract divide or multiply them?
(9*9)+9+9+9/9 = 100
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.
The answer depends on what you wish to do with the number. Add or subtract, multiply or divide, calculate square root, whatever. But since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer. The answer depends on what you wish to do with the number.

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…
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.
One way: -- Subtract the discount percent number from 100 . -- Multiply the result by the dollar amount. -- Divide the result by 100 . -- The result is the discounted amount. =============================== Another way: -- Multiply the dollar amount by the discount percent number. -- Divide the result by 100 . -- Subtract the result from the original dollar amount. -- The result is the discounted amount.
Does an inequality sign change in an equation when both sides are multipled or divided by negative number?
You get the same result if you multiply a number by 7 or if you multiply the number by 2 and then add 20 Find the number?
You are thinking of a number you multiply it by 5 and add 22 you get the same answer if you multiply by 2 and add 76 What is your number?
I like this one.... think of a number multiply by 2 add 12 subtract 4 divide by 2 subtract the number you thought of and the answer is 4 it always works its a mathematical certainty once you have the number 4 you can add subtract etc to your hearts content and make any new number provided you remember the answer yourself.
There are two ways - that are essentially the same. Method I: Subtract the percentage from 100. Multiply this number by the original price and divide by 100. Method II: Multiply the original price by the percentage and divide by 100. Subtract the result from the original price. For example, original price = 300, and you want 15% less. Method I: 15% from 100% = 85% 300*85/100 = 255 Method II: 15% of 300 =…
The difference is that instead of the sign "=", an inequality sign, for example "<" (less-than) is used. For solving inequalities, you can add, subtract, multiply or divide both sides by the same number, similar to an equation; however, if you multiply or divide by a negative number, the direction of the inequality changes. For example, "<" becomes ">".
