What 4 single digit numbers add up to 24?
28
How many two-digit numbers have digits that add up to 10?
To make the list of two-digit numbers with digits that add up to 10, first write the pairs of single-digit integers that add up to 10. They are (1,9), (2,8), (3,7), (4,6), (5,5). Then recognize that each of these pairs of numbers, except 5, can be combined in two different ways to make two-digit numbers that satisfy the problem. 19 and 91 28 and 82 37 and 73 46 and 64 55 So there are nine two-digit numbers with digits that add up to 10.

What is the sign for multiplication and addition?
If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative. Multiplying a positive number by a negative number, or a negative number by a positive number, results in a negative result.For addition, if you add two positive numbers, the result is positive. If you add two negative numbers, the result is negative. If you add a positive and a negative number, the result depends on which of the numbers has the greater absolute value. For example, if the positive number has the greater absolute value (distance from zero), the result will be positive.If you multiply two numbers, the result will be positive, if both factors are positive, or if both are negative.
