In math terms, we say we can multiply an m × n m × n matrix A A by an n × p n × p matrix B B. (If p p happened to be 1, then B B would be an n × 1 n × 1 column vector ...Solve your math problems using our free math solver with step-by-step solutions.

Our math solver supports basic math, pre-algebra, algebra, trigonometry, calculus and more. The three integrals from 1 to 2, from 2 to 4, and from 4 to 8 are all equal. Each region is the previous region halved vertically and doubled horizontally. Extending this, the integral from 1 to 2 k is k times the integral from 1 to 2, just as ln 2 k = k ln 2. Calculus. In real calculus, the derivative of 1/x = x −1 is given by the power rule ...x squared is a notation that is used to represent the expression \(x\times x\). i.e., x squared equals x multiplied by itself.First we prove an intermediate result. Subtract 0 × 0 0 × 0 from each side to get 0 = 0 × 0 0 = 0 × 0. Now we are ready for the final kill. = 1 × 1 + 1 × (−1) + (−1) × 1 + (−1) × (−1) = 1 × 1 + 1 × ( − 1) + ( − 1) × 1 + ( − 1) × ( − 1) Add 1 1 to each side to get 1 = (−1) × (−1) 1 = ( − 1) × ( − 1). 25.6k 4 ...Sounds tough, but once you have mastered the 10× table, it is just a few steps away. Firstly, 11× is mostly easy: from 11×2 to 11×9 you just put the two digits together. 11×2=22, 11×3=33, ..., 11×9=99. And of course 2×, 5× and 10× just follow their simple rules you know already. So it just leaves these to remember: .
