When you add two odd number together is your answer an even or an odd number?
Always an even number. Think of an odd number as an even number plus a half. Add them up and the two halves make an even.
Can the product of two prime numbers be an even numbers?
Yes, it can. Examples are 2 and 5 to make 10 and 2 and 7 to make 14. If your question was if they could make an even prime number, the answer is no. Two is the only even prime number.
What is number seven?
The number seven is 7 which is a Prime number.
Is an even number times a odd number an even number?
Yes, you would get an even number. I'll use an example to tell you why you get an even number. Let's use 7 times 4. Let's say I set out 4 groups of 7 blocks. The first 6 blocks in each set would be an even number of blocks, so we can set those to the side since we already know they make an even number. This leaves us with one block per group left (the odd block). If we combine all the "odd" blocks, we would have four. These four blocks would make 2 sets of 2 blocks, thus giving us an even number of blocks. In other words, an odd number times an even number is even because the item that makes a number odd would match with an item that is making another number odd, thus those two "odds" match up to make an even number.
What if you multiply an even number and even number what kind of number do you get?
If you multiply any even number by an even number, the product is an even number.
