I am thinking of 2 numbers whose sum is 5. If I add the second number to twice the first number, I get 2. What are the two numbers? What can be multiplied to get 60 but add to get -19? One number exceeds another
The sum of two whole numbers is 19. The product of the numbers is 84. What are the two numbers? Is there a set of two numbers that add to be 1 and multiply to be 1? Two numbers when multiplied = 36. One number is x and the other is greater than x by 5. If the two numbers...
For example, when adding or subtracting numbers, you can pair up odd numbers with odd numbers and even numbers with even numbers to make calculations easier. For multiplication and division questions, you can also use the fact that odd numbers always give odd results when multiplied together, ...
How many whole numbers between 1 and 100? How many whole numbers are there between 27 and 46? How many whole numbers are there between 32 and 53? How many integers between 1 and 140 are integer multiples of 2, 5, or 7? What two integers can be multiplied to -420 but added together...

3600=6×6×10×10=60×60, which satisfies the condition of perfect square numbers. So, 3600 is a perfect square number.4. What is the smallest whole number to be added to 55 to make it a perfect square?Solution: The next closest perfect square number to 55 is 64, which is the ...
Any number multiplied by 5 will end with a unit digit of either 0 or 5, depending on the other number involved in the multiplication. However, since we are multiplying odd numbers, the unit digit will remain 5. Step 5: Conclude the unit digit of the product ...
The identity property of an integer states that any integer added to zero will result in the same integer. Similarly, any integer multiplied by one will give the same integer. So, for any integer a: $a + 0 = 0 + a = a$ $a \times 1 = 1 \times a = a$ ...
The number in your tax code shows how much you can earn before you have topay tax. The number is usually multiplied by 10, and this gives you the total amount of tax-free income. So the ‘1257’ in the example above represents £12,570. ...
