It is: 1 times 13 = 13 which is a Prime number
It is: 1 times 13 = 13
3*13=39
1 x 91, 7 x 13.
104. If there are an even number of minus signs in a multiplication, ignore them!
As far as i know its 2*13=26
It is: 1 times 13 = 13
The multiplication that equals 13 is 1 multiplied by 13, or 13 multiplied by 1. Additionally, there are no other pairs of whole numbers that can be multiplied together to yield 13, as it is a prime number.
It is: 13*13 = 169
1 and 13.
I think its 104 because if you do 13 x 8 = 104 you will get that answer and also if you know your multiplication facts.
13x1=13 13x2=26...etc
It is: 1*13 = 13 because it is a prime number
13*125
3*13=39
10*1.3 = 13 is one of infinitely many possible answers.
The number 39 can be expressed as a multiplication problem using the factors 3 and 13, since (3 \times 13 = 39). Additionally, it can also be represented as (1 \times 39) or (39 \times 1). These factors demonstrate the different ways to compose the number 39 through multiplication.
To find a prime number. #1. If an even number (ending in 0,2,4,6,8,) it is NOT a prime number. It is a composite with a factor of '2' #2. An ODD Number ending in '5' is NOT a prime number., It is a composite of '5' #3. If the digits of an ODD number sum to '9' , then it is NOT a prime number, It is a composite of '9' #4. To test for a prime number, divide by '3' & '7' , if there is a remainder to either division it is a prime number. The answer MUST NOT be a whole number. Then it is possible prime number. e.g. 839 #1. NOt EVEN #2 . Does NOT end in '5' #3. The digits sum to 8+3+9 = 20 (Does not divide by ;9;) #4. 839/3 = 279 remainder '2' or 839/7 = 119 remainder '6' So 839 is a prime number.
