(10 + 1) times 5 = 11 x 5 = 55
-2
10 + 7 + 0.7 + 0.01 = 17.71
They add up to 10.042
4 plus 6 plus 3 equals?Add 4 and 6 and get 10, then add 3 and 10 and get 13. Therefore, the answer to 4+6+3 is 13.
One method is (10×4)+(5×3) = 55 (or mentally add up from left to right).
If we add -10 and -2 and -4, we get -16.
When you add -9 and +10, you get (+) 1.
10 X 10 = 100 You can do this four ways: You can do it mentally in your head or you can add them all up on paper by lining up the numbers correctly with each other. You can use a calculator and that is the easiest way. An alternate way is to multiply 10 by 10.
It is so very simple and quick to get the answer if you use the calculator that comes with your computer. But since you are not able to do so, the answer is 25.
132 is the answer. add 40 and 10 in hour head and get 50. 50 and 75 equal 125. finally add on 7 to get 132.
10 add 2 / 10+2
1/5 plus 1/2 is the same as 2/10 plus 5/10 = 7/10
