a⋅0=0 The product of any number and 0 is 0.

To estimate the result of multiplication (product), round the numbers to some close numbers that you can easily multiply mentally. One method of estimation is to round all factors to the biggest digit (place value) they have. For example, estimate 365 × 24. Round 365 to the nearest hundred, and 24 to the nearest ten.

When speaking mathematically, the term product means the answer to a multiplication problem.

The result of multiplying 4 with 4 is called the product. Thus, the product of 4 and 4 is as follows: 16. In other words, we find the product of 4 and 4 by simply calculating 4 times 4 which equals 16. Pretty easy huh?

The product of any number and 1 is equal to that number. The number 1 is often called the multiplicative identity. The numbers 1, 2, 3, 4 and so on. Also called counting numbers.

The product of 15 and r means to multiply, (15r) represents that. Decreased by p is meaning that it’s taking away, or subtracting p. That’s why it is – p.

The first 1000 prime numbers

For 11, the answer is: yes, 11 is a prime number because it has only two distinct divisors: 1 and itself (11). As a consequence, 11 is only a multiple of 1 and 11.

A prime number is a whole number greater than 1 that can only be divided by itself and 1. The smallest prime numbers are 2, 3, 5, 7, 11, 13, 17, 19 and 23.

1 is the smallest natural number.

999

102

The first is smallest natural number n so the smallest natural number is 1 because natural numbers go on. The smallest whole number is 0 because whole number start from zero and the go all the way up to Infinity. So they start from zero and up to Infinity largest natural number.

The three smallest digits are 0, 1, and 2. We can’t repeat, so we’ll have to use one each of those.

The greatest 3-digit number divisible by 7 is 994. Therefore the three-digit numbers are 105, 112, 119, 126,………….. 994. This is an Arithmetic progression with first term a=105, common difference d = 7, last term =994.

Rule: A number is divisible by 3 if the sum of its digits is divisible by 3. 375, for instance, is divisible by 3 since sum of its digits (3+7+5) is 15. And 15 is divisible by 3. 1+2=3 and 3 is divisible by 3.

105

The number of three-digit numbers divisible by 3 are 3999 − 3102 + 1 = 333 − 34 + 1 = 300 .

The sum of all 3-digit numbers divisible by 11 is 44550. What is the smallest three digit number divisible by 11? The smallest or lowest 3-digit number divisible by 11 is the first number on the list above (first 3 digit number divisible by 11). As you can see, that number is 110.

70336

100 three digit

105, 112, 119,….,994 are 3 digit numbers divisible by 7.

Clearly, the numbers between 250 and 1000 which are divisible by 3 are 252, 255, 258, …., 999.

The number series 1, 2, 3, 4, . . . . , 999, 1000. Therefore, 500500 is the sum of positive integers upto 1000.

Step-by-step explanation: 246. This will have all numbers divisible by 6 between 100 and 250. tn = 246.
