The mean is the average of the numbers. to find the mean add up the numbers and divide by how many numbers there are
1 An integer is a number that has no fractional part, and no digists after the decimal point. An integer can be positive, negative or zero. example 12, 34,-4,0 etc.
2. A natural number is a number that occurs commonly and obviously in nature. As such it is a whole, non -negative number. The set of natural numbers, denoted N, can be defined in either of two ways : N = (0,1,2,3,.......)
Just draw a graph and plot them on the graph then count how many squares (in short) there is between them.
7 bicycles dived by two mopeds = 3.5
$152 x 3.5 = $532
your answer is $532.
-9 × 3 - 4² = -27 - 16 = -43
3² + 2² = 9 + 4 = 13
(-9 × 3 - 4²)/(3² + 2²) = -43/13 = -3 4/13
