What number is reversed if you multiply it by 4?

To summarize, the only number that solves the puzzle is 2178. By a similar logic, we can find the six-digit number that when multiplied by 4 is equal to the original number with its digits in reverse order. Each of the intermediate carries must be 3, and so the number is 219978.

How will you get the reverse of 21978 by applying any of the four basic operations in mathematics?

=> The reverse number of 21978 is 87912. => P = 4.

Can multiplying 3 numbers be done in any order?

It doesn’t matter which order you use to multiply numbers. The answer is always the same.

Does the bigger number go first in multiplying?

It’s a good habit to always write the larger number on top. The problem will be harder to solve if you don’t. Next, write the times sign to the left of the numbers. Always set up stacked multiplication problems the same way: with the larger number on top… and the right digits lined up.

What number do you multiply by 4 to get 100?

4 times 25 equals 100. This can also be expressed as 4 x 25 = 100. The best way to figure out what 4 x ‘unknown’ = 100 is, is to divide 100 by 4….

What is the reverse order of 1234?

For Example input number is 1234 after reversing number will be 4321.

Which other numbers between 700 and 800 can be formed from a number plus its reversal?

Beth and Emily from Culford school successfully found the 10 numbers between 700 and 800 which can be written as the sum of a number and its reversal, and spotted some patterns: 706, 707, 726, 727, 747, 746, 767, 766, 787, 786.

When you multiply numbers in any order you arrive at?

This is called the commutative property of multiplication. This is called the associative property of multiplication. unambiguously without any parentheses. Combining these two properties, we can multiply numbers in any order and always get the same result.

What is the order of multiplying?

We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What is carrying multiplication?

If carrying is involved, you will take the carried value and place it in the column to the left. So if you were multiplying numbers in the tens column and you needed to carry a “4”, you would place that “4” in the hundreds column.

Does multiplying always make numbers bigger?

It is a very common misconception that multiplication makes things bigger. But sometimes multiplying numbers together gives a smaller answer, e.g. 6 x ½ = 3. It depends on which numbers are multiplied together. Multiplying by 1 gives the same number, e.g. 16 x 1.

How do you multiply whole numbers without carrying 1?

No need to carry the 1. Move one place to the left. Multiply the tens digit in the bottom number by each digit in the top number. This is the last number to multiply so write the whole number answer. No need to carry the 1. Once you add the columns you can see the long multiplication result: 234 × 56 = 13104.

Which is correct 4987 or 4987?

Consider that you have the number 4987. This number “4987” in its current form is called expanded notation. To convert it into the standard form, you need to portray it as a power of 10. In accordance with the expression shown above, the left hand and right-hand sides are equal. Hence, the standard notation is correct.

Is the number 4987 expanded or standard notation?

This number “4987” in its current form is called expanded notation. To convert it into the standard form, you need to portray it as a power of 10. In accordance with the expression shown above, the left hand and right-hand sides are equal. Hence, the standard notation is correct.

What is 10x + y = 2178?

So necessarily X is greater than 100 (to make it a 4 Digit Number) and typically Y is anything. Applying the given conditions, and solving for X and Y, we get X as 132 and Y as 858. So the actual Number which is 10X + Y is nothing but 1320+ 858 = 2178!
