How to use the tape.equal function in tape

var results = where(function () {
    /*** 
      leftInput |    b  |  andTheAnswerIs
        1000    |  1000 |  1000
         12     |    24 |  24
      451       |  2    |  4451
      4         |  8    |  7
    ***/
    
    tape.equal(Math.max(leftInput, b), andTheAnswerIs, 'max(leftInput, b)');

    // tape does not run the second assertion if the first one has failed.
    tape.notEqual(b, 2, 'b != 2');

    }, { tape: test, intercept: 1 });

var results = where(function(){
    /***
    | a | b | c |
    | 1 | 2 | 2 |
    | 7 | 5 | 7 |
    ***/
    
    tape.equal(context.log, 1, 'should see context.log');        
    
  }, { tape: test, log: 1 });

results = where(function(){
        /***
        | a | b | c |
        | 1 | 2 | 2 |
        | 7 | 5 | c |
        ***/
        tape.equal(Math.max(a, b), c, 'Math.max(' + a + ',' + b + ') should be ' + c);
        
      }, { tape: test, intercept: 1 });
    }
