For all integers m and n if mn is an even then m is even or n is even?

If m * n is even, it can be expressed as m * n = 2 * t, where t is natural number.
Either m or n has to provide factor of 2 for the right side of equation, so it basically means at least one of them has to be even.

What is m x n?
m *n (m multiplied by n) would be mn.
What is the side included between the angles M and N of triangle MNP?
The side is MN although it may be denoted by p (lower case).
How do you prove by algebra that if you add two even numbers you get an even number?
You use the definition of even numbers which says it is a number of the form 2n for some integer n, and you take two of them, say 2n and 2m and add them and see that you have 2n+2m=2(n+m) and since n and m are integers so is n+m so lets call it p so the sum is 2p and this is even by definition of even numbers
Mn - 4m - 5n plus 20?
(m - 5)(n - 4)
Does MN equal NM?
If M and N represent numbers and are to be multiplied, it doesn't matter if you multiply NM or MN. Just think, 7x8 and 8x7 still = 56.
What are all the terms in the expression MN plus m plus 5 and which is a constant?
MN m and 5 are the terms. 5 is the costant
WHY IS AN ODD NUMBER TIMES AN EVEN NUMBER EVEN?
Suppose m and n are integers. Then 2m+1 is an odd number and 2n is an even number.(2m + 1) * 2n = 4mn + 2n = 2*(2mn + 1). Since m and n are integers, the closure of the set of integers under multiplication and addition implies that 2mn + 1 is an integer. Thus the product is a multiple of 2: that is, it is even.

Can you prove If m n and p are three consectuive integers then mnp is even?
If m, n, and p are three consecutive integers, then one of them must be even. Let's say the even number is m. Since m is even, it is divisible by two, and so can be written as 2*k, where k is some integer. This means that m*n*p = 2*k*n*p. Since we are multiplying the quantity k*n*p by 2, it must be divisible by two, and therefore must be even.
How do you factor Mn - 4m - 5n plus 20?
mn - 4m - 5n + 20 = (mn - 5n) - (4m - 20) = n(m - 5) - 4(m - 5) = (m -5)(n - 4)
Is MN an abbreviation for millions?

How do you prove the integers of the form 3n plus 1 is close under multiplication?
Suppose x and y are any two elements of the set.Then x = 3m + 1 and y = 3n + 1 for some integers m and n. Then x*y = (3m + 1)*(3n + 1) = 9mn + 3m + 3n + 1 = 3*(3mn + m + n) + 1. Since m and n are integers, mn+ m + n is also an integer = p, say. Then x*y = 3p + 1. That is the set is closed under multiplication.
Why is a even number minus an even number even?
Suppose x and y are even numbers. Then x = 2m and y = 2n for some integers m and n.x - y = 2m - 2n = 2(m - n) [distributive property of multiplication over addition/subtraction] = 2k where k is an integer [closure of integers over addition/subtraction] Thus x - y is an even integer.
What is m x n?
m *n (m multiplied by n) would be mn.
