7. Make up 6 questions to the text and answer them. Adding, subtracting, miltiplying and dividing the whole numbers

The result of addition of numbers is called the sum or total of the numbers. The numbers to be added are called the addends . In adding a series of numbers, begin with the column at the right. If the sum of a column of digits is ten or larger, carry the tens digit and add it to the sum of the digits in the next column to the left.

In subtracting whole numbers, the number which is to be diminished is called the minuend; the number subtracted is called subtrahend. The answer is the difference between the minuend and the subtrahend and it is called the remainder, or difference.

In multiplication, the number by which you multiply is called the multiplier, the number being multiplied is the multiplicand.

The number resulting from the multiplication is called the product. The product of any number multiplied by zero is zero. The product of any number which is multiplied by one is the same number. The order in which numbers are multi plied does not change the product.

In division, the number that is to be divided is called the dividend. The number by which the dividend is to be divided is called the divisor. The answer is the quotient. The remainder is what is left over after the dividend has been divided into equal parts. If there is a remainder, it may be written over the divisor and expressed as a fraction in the quotient.

NOTES:

the numbers to be added - числа, которые нужно сложить

is to be diminished - должно быть

the same number - то же самое число
