Simplify 1 6 - 5 We add 1 and 6 to get 7. A ddition and S ubtraction left-to-right Divide and Multiply rank equally and go left to right. When seeing an exponent solve it first after solving the brackets.
However if I present you with the following equation which is a model of the problem above you might have a tendency to add 3 to 1 and multiply the result by 2.
We skip this one since there are no parentheses in our problem. While creating mathematics one should take care that no contradictions are produced. 4 1 2 1 2. First you have to set it to the same power of 10.
