8 x (4 + 2) = 48
8 times 3=24
no, you multiply first. For example 2 + 3 x 4 + 5 = 2 + 12 + 5 = 193 +
A Sum is the anwser to a Question when you ADD two numbers like 23 + 1 = the sum of the question.
To calculate the sum of the numbers 1 to n, the formula is: sum = n(1 + n) / 2 So, an equation to find the sum of the integers 1 to 2010 is: sum = 2010 x (1 + 2010) / 2
0.5
Avreage = Sum/number of values So 10 = sum/2 Multiply both sides by 2: 20 = sum

Multiply sum by 2.
No, the Sum of two reciprocals isn't 1. However, the PRODUCT of two reciprocals is 1. For example, if you multiply 1/2 with 2/1, you'd multiply the two numeraters, which would be 1X2=2, and the two denominators, which is 2X1=2. this would cause the answer to be 2/2, or 1.
the sum is example 2+2=4, 4 is the sum
Factors are the numbers you multiply together. For example, in the equation 2 times 3 equals 6, the 2 and the 3 are both factors of 6.
The answer is 24.
The associative property means that in a sum (for example), (1 + 2) + 3 = 1 + (2 + 3). In other words, you can add on the left first, or on the right first, and get the same result. Similar for multiplication. How you use this in an equation depends on the equation.

Set up an equation using x for the integer. The equation would be: x/(-4+6)=-15 Firstly find the sum of -4 and 6. It would be 2. The equation is now: x/2=-15 Multiply both sides by 2. This means that: x=-30 Plug it back into the equation to check: -30/(-4+6)=-15 -30/2=-15 -15=-15 It works therefore -30 is the integer that when divided by the sum of negative 4 and positive 6 equals negative 15.

To convert any decimal to percent, simply multiply the decimal by 100.Putting your example into the equation we get: 0.2 × 100 = 20(%)
